What does 2-Acetyl-1-pyrroline smell like?

Hot buttered popcorn, fresh bread crust and the warm cereal sweetness of basmati rice and pandan leaf. Threshold near 0.02 ppb, among the lowest of any known odorant, and nothing else reproduces this note; unstable neat, so it is supplied only as a dilute solution and dosed in traces.

Every regulatory join - IFRA, GHS, allergens - is by CAS number, and a material can supply one through its constituents as well as its own row, so of the 569 materials carrying no CAS number the 244 without a constituent table are the ones that return "nothing known" rather than "nothing applies". The blotter hours are sourced rather than measured by us, and the app labels every one of them an estimate. There is no physical chemistry on a row: no molecular weight, no vapour pressure, no boiling point. The longer answer, or the whole catalog counted.
