2-Monostearin CAS 621-61-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 358.56 g/mol gives 2-Monostearin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-Monostearin (CAS 621-61-4), a certified reference material (molecular formula C21H42O4, MW 358.56 g/mol) for analytical method development and quality control.

2-Monostearin (C21H42O4) 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.

CATO manufactures 2-Monostearin under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
