Sources/Uses

A mixture of di- substituted saturated decanoic acids; Used as a pre-harvest desiccant for onion foliage; [ChemIDplus] Used as an intermediate in the chemical industry; [IUCLID] Permitted for use as an inert ingredient in non-food pesticide products; [EPA] "Neodecanoic acid is a mixture of carboxylic acids with the common structural formula C10H20O2, a molecular weight of 172.26 g/mol, and the CAS number 26896-20-8. . . . Neodecanoic acid is used primarily as an intermediate to make other chemical products. For example, metal salts of neodecanoic acid can be used in a variety of applications such as paint driers, polyvinylchloride stabilizers, or polymerization initiators. Ester derivatives of neodecanoic acid are used in surface coatings and cement additives. In its neutralized form, neodecanoic acid is used in metalworking fluids." [Wikipedia]
