chloromethanesulfonic acid CAS 40104-07-2 chemical structure

Description

CATO supplies chloromethanesulfonic acid (CAS 40104-07-2), a certified reference material (molecular formula C10H18O, MW 154.25 g/mol) for analytical method development and quality control.

chloromethanesulfonic acid (C10H18O) contains a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.

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.

CATO manufactures chloromethanesulfonic acid 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.
