Chemical Structure

Methyl Malathion CAS 71133-16-9 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

Methyl Malathion (CAS 71133-16-9), molecular formula C9H17O6PS2 and molecular weight 316.33 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Methyl Malathion is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

CATO manufactures Methyl Malathion 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.
