Of course! However, I've never bought Sodium Cyanide (I think you just gave me an excuse to spend the money and buy it ). For the others, in about two hours I'll put the photos here.
While we wait, what do you wish to know more? If you want to know about more OTC chemicals just ask away...
EDIT
The photos are here.
Hydrogen Peroxide 50%

The bottle is mine as is the label. For further proof, my syntheis of Nitrocellulose (with said acid) and a video of it burning:

I'm kind of jealous of you for living in Portugal now...

You know, the United States is really not that bad either. I mean, sure there's regulations and it's hard to find a few things, but for most general
chemistry stuff, it's pretty free and easily accessible, even in Texas.

Wow. Portugal here I come! LOL at the comic sans nitric acid label.
Any idea on the purity of this stuff? (As in any impurities present besides the obvious water.)
Also, how's the supply of organic reagents there?

Anything wrong with comic sans my times new roman conservative friend?
The Nitric Acid I use is completely pure (besides water, but I don't consider it an impurity per say). What were you referring to? All the chemicals
mentioned are technical grade but have high purity. In fact, they all seem to be lab grade.
What kind of organics are we talking about?

I actually kind of like Comic Sans, but I've grown so used to generic all caps, generally very serious looking labels for reagents, whether they're
intended to be or not, that such an innocent looking font for the label of something like nitric acid seems kind of facetious in a humorous way. I
usually type with Arial by the way, Times New Roman is too boring, that, and Arial is set as the default font for my usual word processor, so I'm used
to it.
I understand that water usually isn't considered a real impurity rather than a diluent, I was referring to things along the lines of totally different
chemicals in the mix. Such as thiophene being a common impurity in non-reagent grade toluene, carbonized organic crap in cheap sulfuric acid, sugars
or other organics present in vinegar, and stuff like that. What I guess I was asking about in particular was any dissolved nitrogen oxides in the
nitric acid, as that is very common in higher concentrations, and any other acid or additives besides nitric in the mix. Here in the US, the only OTC
nitric acid that I've seen is mixed with phosphoric acid and some kind of surfactant. That's very impressive that they seem to be that pure.
Regarding the organics, I'd be curious if benzene is available over there, I have never seen benzene for sale OTC here in the US. If toluene, xylene,
and etc are sold over there like they are here, I'd be curious of how pure they are. As I mentioned, at least here, thiophene is very common in
toluene. Following suit: xylene, methyl ethyl ketone, acetone, naphthalene, ethyl acetate, ethylene glycol, polyethylene glycol, and etc are usually,
or at least fairly often, contaminated with something in minor to considerable concentration like some other ethers, petroleum distillates, and or
some other additives. Have you ever seen any plasticizers like diethylhexyl phthalate available? Anything really exotic or rare?

@APO,
Sorry for the late response. So, let's start.
Benzene: Completely unavailable. The all carcinogenic thing hit my country and they ended up removing it from the market.
Xylene: Sold pure (isomeric mixture).
Toluene: The best I can find is a mixture of Methyl Ethyl Ketone (~40%) and Toluene (~60%). Seems to be free of any other major contamination. It can
also be found as a mixture with other crap in it in many paint thinners formulations.
Methyl Ethyl Ketone: Like described above (Toluene).
Acetone: Can be found in ANY grocery store. Sold under the name Acetone. Usually used has a Nail Polish Remover, which is contaminated with water and
glycerin. It can also be found, in pure form, in drug stores (to be used as paint thinner of some sort).
Naphthalene: Available at any grocery store as Mothballs.
Ethyl Acetate: Some Nail Polish Removers have it, instead of having acetone. Never really looked for it anyway.
Ethylene Glycol: Antifreeze. Never cared to look anywhere else.
PEG: Never looked for it.
Diethylhexyl Phthalate: We have vinyl gloves over here.
I don't use this store but it reflects what I can obtain here in Portugal under the "exotic" category:

There are many more available on that site or other stores. Those seemed to be the most interesting ones. Feel free to ask for something specific or
any more information
