Application
Aldehyde C12 MNA (2 Methylundecanal) is a classic and versatile aldehyde widely used in the fragrance and flavor industry. First synthesized in 1904 by Georges Darzens, it gained fame as a key component in Chanel No. 5 and remains a cornerstone of modern perfumery. In fine fragrance compounding, it provides powerful aldehydic notes with fresh citrus, ozone, and amber nuances, making it suitable for all types of perfume formulations. It performs exceptionally well in floral, woody, ambergris, and tobacco accords, and offers excellent fabric retention. It is widely used in perfumes, cosmetic care products, soaps, detergents, and household care items. In flavor applications, Aldehyde C12 MNA is approved by FEMA (No. 2749) and JECFA (No. 275) as a food flavoring agent. At low concentrations, it imparts honey, nutty, and fruity notes for citrus, coconut, apricot, and pineapple flavor profiles. At high concentrations, it exhibits a pungent, fatty character. It is found naturally in trace amounts in kumquat peel oil.
