What does 2-Methyl-2-pentenal smell like?

Powerful aldehydic green, grassy and pungent, with a ripe-cherry fruitiness and an alliaceous earthy edge underneath. Traces add green-fruit realism and a vegetal bite to fruit and green accords; it fades from a strip within the hour and IFRA restricts it very tightly, so work from a dilution.

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.
