I got a bottle of propionic acid today. It smelled very interesting, like Parmesan cheese. Not like feet as I expected.
Of course that's just the bottle itself, don't want to open it!

Worst and best all in one
At room temperature B4H10 is a colorless liquid or gas
having a peculiar smell, highly disagreeable odor; when
highly diluted, smells like chocolate. Its odor is still more
disagreeable than that of B2H6; which is probable do to
the fact that B4H10 is not decomposed at the moist
mucous membrane of the nose as rapidly as is B2H4. When
inhaled, a few bubbles of B4H10 cause headache and nausea.

didn't have the patience to read past page 2, but...
butanol!!!....and 2-mercaptoethanol is pretty bad too
best smelling: isoamyl acetate, salacylate, or vanillin

Be VERY, VERY careful indeed when working with hydrogen selenide!!! I found out why - THE HARD WAY!!! By accident I exposed myself to a HIGH
concentration of the gas. The first sign of danger was the change of odor from rotten radishes / 'gas' to STRONG ODOR OF ROTTEN EGGS. I stupidly
ignored this warning. Suddenly without any further warning: my nose started STINGING / BURNING UNCONTROLLABLY - NO MATTER HOW QUICKLY I RUSHED TO THE
NEAREST WINDOW. Still the UNBEARABLE STINGING / BURNING WOULD NOT GO AWAY, OR EVEN LESSON IN THE SLIGHTEST!!! SEVERAL hours later the stinging /
burning in my nose was tolerable and had almost gone - only to be left with a nasty cold that took at least a few days to get over. I could have only
been exposed to the gas for a few minutes at the most - while I was transferring some aluminum selenide from one container to another. By the way -
always store and handle aluminium selenide away from even air!! Hydrogen selenide has got to be the worst smelling compound in my opinion. This is not
so much because of its awful smell - but because it BITES your poor nose and does not let go until after several hours later - when you are then left
with a cold that takes at least a few days to shake off!!

Isoamyl acetate smells pretty good, but in general esters are some of the best smelling chemicals.

Fractional distillation probably, but I'd rather buy some pure I have some
pure DEE. About a litre.

Researchers were formerly much more adventurous in employing their sense of smell and taste in the investigation of new compounds. I still find it
difficult to believe that researchers actually decided to taste ethyl perchlorate, despite the fact that the compound is an
extremely dangerously sensitive explosive, highly brissant even in very minute quantities, and a potentially deadly [poisonous] alkylating
agent. Ethyl perchlorate has a "sweetish pungent taste, somewhat resembling that of cinnamon." Another source described that it has a "very pleasant
odour and a sweet taste that changes to a burning taste like cinnamon."

Unbelievable.. But the positive fact is, that we know how it smells/tastes without doing any damage to ourselves Someone tried it before, so we don't have to

I'd like to say Chlorine smells the worse, but after getting use to it, it's not so bad. The most it does it harden the mucus in my nose on first whif
of it.
But by far the worst is Glacial Acetic acid. Just nasty to even be around.
Not so sure on a good smell, Probably Citric acid. I love citric type flavors. QED: I love limes and lemons.

One compound which really is annoying is POCl3. I distilled some POCl3 in order to make it pure and now I have a smell in my nose which remains, even
a few hours after I did the distillation. A similar effect I also noticed with PCl5 a year ago or so. The smell is not really bad, but it is bad that
it remains in the nose hours after exposure. I only had a small whiff of the vapor, so there is no irritation, just a smell.

Actetic anhydride, due to its volatility, is even more pungent! Yes, acetic acid is has an unpleasant smell (with a strong odor of vinegar), but it is
really not so bad once you become accustomed to it.
When chloroform is heated with a primary amine (such as ethylamine CH3CH2NH2) in the presence of KOH, isocyanides are formed. These isocyanide have a
very bad smell, resembling boiled cabbage, but much worse. Even a slight whiff will cause trouble breathing in most people.
Methyl isocyanate is toxic. Not sure about the others.

Guess I shouldn't have said refluxing but rather hot DMSO, sorry for bad vernacular. The rxn I attempted with it evolved CO2, so it made it appear as
though refluxing.
Also when I said 'mostly everything else I agree with' was about agreeing with what other people were saying.

Now I realised, that TATP has also a good smell. It smells like some commercial bleaching agents (SA8 - NA2CO3 × 1.5 H2O2). It is kinda strange, that
the compound with explosive properties has also a good smell

you got that right brother! the majority of phosphorus compounds i have experienced so far are very unpleasant smelling. i have the phosphorus i made
in a container under water and the bottle reeks every time it is opened. i also find it odd that there is a bit of smoke released every time i open
the bottle...
as for the best smell of all time...i have to say that my smokehouse...or maybe my barbecue grill has it cinched up. some natural lump coal and a
couple chunks of hickory or some apple or cherry wood burning under a brisket for 12-14 hours has been known to make the neighbors nosier than
chemistry experiments ever could.
