Nonanoic acid

Nonanoic acid, also known as pelargonic acid, is a fatty acid found in various plants and essential oils. It has a sharp, fatty, and slightly cheesy smell at high concentrations, but in dilute solutions, it can contribute to more complex floral or citrus notes in perfumery.

Used in the creation of esters for perfumery and as an intermediate in the synthesis of flavors and fragrances. It imparts a subtle, fresh note to fragrances when used in very low concentrations.
