Methyl arachidate is a methyl ester of arachidic acid, a long-chain saturated fatty acid derivative primarily used in organic synthesis, lubricant formulations, and as a reference standard in analytical chemistry. It serves as a key reagent in studies of lipid metabolism and polymer chemistry due to its stable, non-reactive nature under standard conditions. This chemical has a CAS number of 1120-28-1, with the molecular formula CH3(CH2)18COOCH3 and a molecular weight of 326.56 g/mol. It is stored at ambient temperature and carries no signal word for hazard classification. Molekula supplies Methyl arachidate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
