Captopril Methyl Ester CAS 176036-41-2 chemical structure

Description

CATO supplies Captopril Methyl Ester (CAS 176036-41-2), a certified reference material (molecular formula C10H17NO3S, MW 231.31 g/mol) for analytical method development and quality control.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Captopril Methyl Ester is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), Captopril Methyl Ester meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
