What does trans-2-Heptenal smell like?

Pungent green vegetable aldehyde, intensely fatty and oily with fruity apple-skin overtones, filling the rung between trans-2-hexenal and trans-2-octenal. IFRA prohibits it outright as a fragrance ingredient on dermal sensitization grounds, so it is of reference and analytical interest only.

Restricted under IFRA. This material carries a restriction. PerfuMate checks your formula against the 51st Amendment as you build, including the same molecule arriving from several naturals at once. What that covers, and what it does not.

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.
