Sodium Borohydride (NaBH4) For Sale! $0.50/gram

Loptr - 14-6-2018 at 09:48

Hey guys,

I have been sitting on quite a bit of NaBH4 for a while, and have decided to start selling it off. I think I have somewhere around 8kg of it, and will be selling it in multiples of 10 grams.

The current price is $0.50/gram (plus shipping), which might change in the future.

If you want some, get it now.

Send your requests to me via PM.

Peace!

Loptr

Also, if you have something interesting to trade I would be willing to consider it.

I can vouch for Loptr. If you don't have any sodium borohydride, you definitely should pick some up!

Thank you, JJay. I really appreciate that.

Loptr - 18-6-2018 at 16:56

Those that have purchased from me so far, could you do me a favor?

When you get the shipment could post a review or pics. Something to drive up interest? I would really appreciate that.

Tdep - 18-6-2018 at 17:06

Do you ship international? Understandable if you don't, no stress

I was wondering the same thing. Not that I have a need for sodium borohydride at the moment. But if an aussie order was going ahead I would piggy back onto it.

Loptr - 19-6-2018 at 18:35

Next set of orders going out tomorrow.

This is still going on, so get it while its available.

Have a Question? Send me a PM.

I received mine today, but it's too late to be doing any sort of measurements on it or analysis. It was well-packed in an HDPE bottle with the cap taped shut, heat-sealed in a plastic bag (all nicely padded and packed for shipping). Communication and shipping were prompt. I am very pleased with Loptr's service, and I would recommend him to anyone else looking to pick up some NaBH4 at an excellent price.

Anyone have suggestions on simple tests? Hydrogen evolution? Reduction of benzophenone? (I have 500g of benzophenone roughly, because this is what happens when HiMedia has good sales, but it's a many year supply for me.

) I don't have an immediate use for the NaBH4, but I'm open to ideas which could be quickly tested and photographed for posting. (Preferably those with distinct color changes, melting points of products below 250°C, or things I can monitor with TLC.)

A quick non-quantitative test could be nice. Do you have silver nitrate?

weilawei - 21-6-2018 at 05:20

I do. That looks perfect, and I'll give that a whirl after work. Thanks Tsjerk.

woelen - 21-6-2018 at 06:15

An interesting experiment would be addition of a small amount of solution of copper sulfate to 5% ammonia. This gives a deep blue solution with the tetrammine complex of copper(II). Assure that you have excess ammonia.
Then add some NaBH4 to it. Best is to dissolve this in some other ammonia and add this to the deep blue solution.
Does it become colorless at once? Then you have good fresh NaBH4, which is very active. At the surface of the liquid you will see a clearly visible blue color, which gives blue schlieren when you swirl the solution somewhat and these blue schlieren disappear in the solution when there is a little excess NaBH4. It's a nice experiment on its own.

Following their procedure, I give you colloidal silver. I'll type up my lab notes tomorrow, because it's just too darn late. The first photo is not Loptr's packing--I transferred a small amount to a vial for easier use/to avoid degradation of the bulk NaBH4.

The left graduated cylinder is a 1 mM soln. of AgNO3, and the right graduated cylinder is a 2mM soln of NaBH4. The next photo shows the initial addition of ~2mL AgNO3 soln.. The next photo is with the addition completed and stirbar removed.

I transferred 20mL to a vial (this is supposed to be stable at room temperature for months), then returned the stirbar to the reaction cylinder. Continued stirring seems to be producing a color change as per the referenced procedure, but it's hard to tell.

Seems good to me. I'll see how far the color change will go and report back tomorrow.

Thanks Loptr, Tsjerk, and woelen! (I'd like to try your suggestion woelen, but I'll need to make some copper sulfate first.)

Edit: I suspected that stirring was preventing aggregation, so I stopped it briefly, and got an immediate color change. I'd like to do this one again, but only stirring for a short period after the initial addition to catch the red and violet colorations.

My liking for this material, involves using it, in Ethanol, to instantly reduce Chloroplatinic Acid to generate finely divided, highly active, Platinum Black. The "Brown" catalyst.

No waiting, no induction period; ready for use in hydrogenations, in minutes.

Loptr - 4-7-2018 at 04:29

Bumpity bump. :cool:

weilawei - 4-7-2018 at 08:30

Well, I've been sittting on a curiosity for a couple weeks now, between vacation and work. The paper referenced initially suggested that the mixture stirred for a short period would be more durable as a colloidal suspension. However, I've experienced the exact opposite. The mixture stirred for several hours (less full vial) is retaining the suspension better.

Any thoughts on what's going on?

Loptr - 14-7-2018 at 15:15

I am still taking orders for NaBH4.

Loptr - 27-7-2018 at 13:32

Excuse me sir, would you like to buy a kilo of Sodium Borohydride?

arkoma - 28-7-2018 at 14:19

Bump. Great deal and FAST ship.

Daffodile - 28-7-2018 at 14:41

Alright Loptr I U2U'ed you. If you don't ship to Canada its alright albeit I would be frustrated to miss out on these prices.

Mothman - 31-7-2018 at 07:24

Packaging is wonderful, bagged and taped to prevent air exposure. I'll be making some nickel boride (P-1) from this to try my hand at a hydrogenation and/or a dehalogenation. Thank you Loptr for making this reagent available to me at this exceptionally good price!

No problem, Mothman!

Loptr - 29-8-2018 at 17:05

Hey guys, please make sure that your PayPal addresses are correct. I just had my 2nd shipping address correction which is like $16 each time.

NaBH4 is still available for sale.

That’s good to hear. I will be purchasing some in the next day or so.

ELRIC - 17-9-2018 at 10:37

@Loptr, I’ve sent you a u2u about my address. But I can’t tell if it’s went thru. I do not wish to incur a $16 fee on you or me. My address on PayPal has been fixed

I got your message. Thank you!

ELRIC - 27-9-2018 at 08:05

Just an update

I received my hydride (thanks loptr). I actually received it two days ago

but because of a recent development, I’ve had to move all my glass away from my

current residence. But I kept my beakers and some test tubes with me. So tonight

hopefully I’ll be able to send some pics. I will also be doing as woelen suggested

with the copper sulfate since I already have some solution laying around. Hopefully

there will be no trouble tonight and I can proceed unhindered

Loptr - 6-11-2018 at 16:38

Any more interest?

Panache - 7-11-2018 at 17:50

Yes check your pm

Loptr - 8-11-2018 at 04:29

Thank you. Sent you a PM.

Loptr - 9-11-2018 at 11:02

Busy week and will be an even busier weekend. Orders are going out on Monday.

Thank you!

Loptr - 9-7-2019 at 16:45

I think I am only going to start only taking 1kg orders until it's all gone.

Loptr is great to do business with, highly recommend his products.

Loptr - 5-9-2019 at 10:31

I have sold all of the NaBH4. Thank you everyone!

Be sure to keep an eye out for another thread I will be creating soon to gather some ideas about a potential group buy. I don't know what yet and wanted to gauge interest.

There will be the potential for a NaBH4 group buy, but only kilogram sized amounts. It really is a pain to break up the packs, and I don't think I would mind reshipping the factory foil pouches.

Anyways, I will keep you guys in the loop.

Just received my shipment; couldn't possibly recommend doing business with Loptr more than I do right now.
Arrived well-preserved, well-packaged, and promptly.
Definitely made my year by making an exception and taking a chance with me, as a new guy; few would've done the same.

After reading Gergel a few years ago, I got a great chuckle over this.

after looking up legalities, unfortunately Australia is a nanny state and NaBH4 "can" and "therefore will be used in illicit drug synthesis" so I'd rather not risk buying some.
