  • Applications

    2-Methyl-3-(p-isopropylphenyl)propionaldehyde (CAS 103-95-7) is an aromatic aldehyde, often classified by perfumers as a “hydrocinnamaldehyde” derivative, that delivers a crisp, green-floral, lily-of-the-valley nuance; it is therefore incorporated into fine fragrances, scented soaps, deodorants, shampoos, body lotions, scented candles and household cleaners to impart freshness and mask base odors; beyond perfumery, the molecule is used as an intermediate in organic synthesis for constructing branched aromatic frameworks destined for pharmaceuticals or functional cosmetics, and it also serves as an analytical reference standard in GC-MS methods monitoring aromatic aldehydes; nevertheless, its handling is subject to IFRA guidelines and local regulations because of potential skin-sensitizing effects at higher concentrations, and manufacturing or storage should be carried out in closed systems with proper ventilation and standard personal protective equipment to safeguard operators and preserve product stability.
