Methyl 12-hydroxystearate (CAS 141-23-1)

Methyl 12-hydroxystearate, identified by CAS number 141-23-1, is a methyl ester derivative of hydroxystearic acid. This compound is characterized by a hydroxyl group at the 12th carbon of the stearic acid chain, a common long-chain fatty acid. The esterification with methanol enhances its solubility and reactivity compared to the parent fatty acid, facilitating its application in various research settings. In scientific studies, Methyl 12-hydroxystearate is extensively used to investigate the physicochemical properties of lipid derivatives, particularly how the introduction of a hydroxyl group influences lipid behavior and interactions. This modified lipid is crucial for studying the dynamics of lipid membranes, including their phase transitions, fluidity, and interaction with other lipophilic substances. Its structure allows researchers to explore the balance between hydrophilicity and hydrophobicity in lipid molecules, which is essential for understanding the assembly and stability of lipid-based structures like micelles and vesicles. Additionally, Methyl 12-hydroxystearate serves as a model compound in the study of lipid oxidation and polymerization reactions, providing insights into the stability and degradation mechanisms of hydroxylated fatty acids under various conditions. This research has broader implications, including the development of bio-based materials and environmentally friendly lubricants and coatings, where such modified lipids play a pivotal role.
