To those who might have missed this:

InnoCentive is currently offering a challenge in "Seeking Compounds with Remarkably Strong Odors." The challenge has a long-lasting deadline (1. September 2012) and has been on for some time already.

Quote:
Material supply of compounds which have remarkably strong odors is desired. The nature of the odor is not important (e.g. pleasant or unpleasant), only its strength. The Seeker intends to award multiple Solvers for each of their qualifying submissions.

Intellectual Property: In return for the Initial Transfer Fee of $500 per compound, you are expected to grant the Seeker only a non-exclusive license to test your compound(s) in their in-house assays and/or use the compound(s) to prepare other compounds for in-house testing.

…there is a human touch of the cultist “believer” in every theorist that he must struggle against as being unworthy of the scientist. Some of the greatest men of science have publicly repudiated a theory which earlier they hotly defended. In this lies their scientific temper, not in the scientific defense of the theory. - Weston La Barre (Ghost Dance, 1972)

I *love* the smell of diacetyl. It is so incredibly strong, too. You can open a bottle and wave your hand over it once to disperse a little vapor, then close it. 20 minutes later, the room will still smell like movie popcorn.

After I finished making it, the entire house smelled of it for a good week. You wouldn't normally notice but when you went out for a few hours and came back, it would smell like someone made popcorn.

I sometimes like to sniff a little bit of isopropyl alcohol. I just love that sharp, tingly odor for some reason. I also like acetone. It's kind of fruity, like a watermelon in my opinion. And also vanillin, of course.

The worst? Sodium metabisulfide and the sulfur dioxide it produces when it touches acid (rotten eggs, makes me want to vomit). Bleach. Ethyl mercaptan (urine) Methyl mercaptan (rotten vegetables). And propionic acid (smells like your armpit on a hot day)

Hypochlorite bleach, mmmmh. Anything halogen-like, really. I've sort of grown up in a pool and I love the smell. Certainly not the best smelling thing in existence, but fairly common.

The smell of "black liquor" on the other hand (pulping 'chemical') makes me want to gag, and it sticks for hours and hours. It's worse than H2S, LPG with mercaptan, and I think only pyridine gets close...

smells like antiseptic to me

Worst: Pyridine, diethylamine, mercapto (species), halogens, acid chlorides

Best: the Oxitocin your mom puts out when I'm laying in bed with her :D:D:D

I got ostracized after a butyric acid spill and cleanup. Phenylacetaldehyde is nice. Phenthyl Br is similar. Saffrole is another nice one. Frank Walters made some synthetic musks that are really nice.

I had a reaction not long ago where sodium hydride was used as a base in dimethylsulfoxide (solvent). There was no problem, the hydride reacted as it should, some fizzing was observed and everything went fine until I discovered something...

The hydrogen reduced a part of the DMSO to dimethyl sulfide what had a smell of rotten cabbage. The distillation and the product workup was horribe, especially when the rest of the DMSO was removed on the rotavap, never again.

Also some other horrible smelling chemicals what I have "met": allyl bromide, butyric acid, ethyl mercaptan, chloroacetyl chloride, bromoacetic acid esters, bromine, isopentyl nitrite, phosphorous oxychloride, methylthioacetaldehyde diethylacetal and the methylthioacetaldehyde (smells like rotten pumpkin), ect...

And afterwards pyridine is aint so bad, there are much worse smelling things.

What about p-kresol? Smells strongly of... Of... Horse or perhaps stables or in fact horse piss.
Another personal worst is n-penthanol, which smells like rutgut liqueur.

I'm considering using butyric acid in a stink capsule that will release a foul smell when it bursts but I read concentrated butyric acin causes burns to the skin. If I dilute it enough to renter it safe will it still stink enough it be effective.

hi, im new to the forum. ive got a first question- is there a section where i could introduce myself to other members? :)



ontopic: dimanganheptoxide is a very, very nice smelling chemical. :)
i dont know what it is that exactly smells, maybe the compound itself but i could imagine that its propably emitting ozone....

btw, is it ok to have a note in my signature saying im selling?
i ll open a topic in the correct section in about 1 or 2 days.




I'm selling some used glass-stuff- volumetric-flasks and chromatography-columns of different sizes!

I say that the three best smelling chemicals are: Vanillin, Methyl Salicate, and Isoamyl Acetate.


As for bad smellin chemicals I really don't like is Putrescine. To me it kind of smells like Rotting flesh and Sewage......

I am personally a fan of the smell of ethyl vanillin, isoamyl acetate, mineral spirits. I detest the smell of phenylacetylene and styrene. Benzotrichloride also smells pretty bad.

Trimethylamine is pretty bad, like rotten fish and it has an odour treshold of about 0.3-0.8 ppb so one drop spilled and your fume hood will smell for weeks to come...
