Methyl Undecylenate ( C12H22O2) : CAS no. 111-81-9

COMMON NAME : Methyl Ester of Undecylenic Acid, Undecylenic Acid Methyl Ester, Methyl 10-Undecenoate , Methyl undecenate , 10-Undecenoic acid methyl ester

Methyl Undecylenate is a linear ester with a terminal double bond, that can be used as a chemical intermediate in the synthesis of aromatic chemicals, of polymers or modified silicones.

It can also be used as such in formulations requiring its anti-odor properties. Methyl Undecylenate can be used as a precursor for undecylenic derivatives in cosmetics. It can also be used as an intermediate in the synthesis of flavors and fragrances, and also in the formulations for its anti-odor properties.

Methyl undecylenate is used as a chemical intermediate in the synthesis of organo-modified silicones for hair care preparations and sun care products.
