Chemicals with a strong smell
Hi there
Do you all have any chemicals that you can think of in a laboratory that give off a very strong smell and should be used under the chemhood
I just used Glacial Acetic Acid today and I had no idea how strong the smell was . from now on I am using it under the chemhood
I have created a list so far, if anyone has anything else I can add that would be great:
* Acetic Acid (Glacial Acetic Acid)
* Acetonitrile
* Ammonia
* Beta-mercaptoethanol
* Cadaverine
* Chloroform
* Formaldehyde
* Hydrogen sulfide
* Methanol
* N-Butanol
* Oleum
*Paraformaldehyde
* Sulfuric acid
*Trimethylamine
*Virkon
Thanks!

The List you wish for would be extremly long.
Many chemicals have a strong smell.
Google 'perfumes' or 'aromatics' to find many many lists.
Edit:
IMHO GAA ranks as 'mild'.
Conc Ammonia ranks as 'sharp, tolerable'
Skatole ranks as 'rank'
and so on : It's too subjective to be useful.

Sulfuric acid isn't that bad compared to many others. There's just too many- there's at least ten more with strongly disagreeable odours I can think
of including several amines without thinking too hard about it. Maybe if you narrow down your list you would get somewhere.

You don't have any phosphines on that list? For shame.
You've also missed aga.
Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.

A shout out for Selenium and Telurium compounds.

Rapopart’s Rules for critical commentary:
1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it
that way.”
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.

Bromine immediately comes to mind. The stench is unbearable.

Sulphuric acid should be too involatile to smell. If you think it smells you are probably detecting impurities.
As far as I am concerned acetonitrile is practically odourless.
Some people lack some odour receptors so there will always be disagreements about what things smell strongly.

Wine Lactone is unusually potent, if the Wikipedia article is correct, listing detection thresholds in the picogram/litre range.

The Mozingo reduction is a rather efficient "teacher" of how thiols actually DO smell that bad.

Thiol something. I remember from a video that a couple drops leaked and someone smelled it a mile away.
Edit:didn't read the first post all the way. I agree with glacial acetic acid ![:D](./images/smilies/biggrin.gif)

Probably a reference to thioacetone:

If the lower figure is correct, then 1000 kg of this chemical would cover the entire surface of the Earth with a detectable odor cloud 200 meters
deep! At least it smells pleasant.
