Affectionately known as Brutal Acrylate.

In scientific terminology, that's some nasty smelling shit. Toxic too.

If there's enough of it spilled you could smell minuscule amounts a mile away easier than an instrument could get a valid reading though.

It's one of those.

The odor threshold of volatile acrylates is orders of magnitude lower than other flammable toxic chemicals like methanol, but the instrumental detectability of acrylates is not really any more sensitive than regular low-odor chemicals by comparison.

IOW the instrument is better at detecting low-odor chemicals than your nose is, but your nose is more sensitive to things that have a very strong characteristic odor like acrylates.
