Chemical Structure

Methyl arachidate CAS 1120-28-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 326.56 g/mol gives Methyl arachidate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl arachidate (CAS 1120-28-1) is a high-purity analytical reference standard with the molecular formula C21H42O2 and a molecular weight of 326.56 g/mol.

Methyl arachidate (C21H42O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
