Cas no 5129-56-6 (Undecanoic acid, 10-methyl-, methyl ester)

Methyl 10-methylundecanoate (C13H26O2) is a branched-chain fatty acid ester characterized by its unique molecular structure, combining an undecanoic acid backbone with a methyl group at the 10-position. This compound is notable for its stability and low volatility, making it suitable for applications in specialty lubricants, plasticizers, and fine chemical synthesis. Its branched alkyl chain enhances solubility in nonpolar matrices, while the ester functionality allows for further derivatization. The compound's defined structure ensures consistent performance in formulations requiring precise molecular weight and hydrophobic properties. It is typically synthesized via esterification of 10-methylundecanoic acid under controlled conditions to maintain high purity.
