Chemical Structure

Mesna CAS 19767-45-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 164.17 g/mol gives Mesna distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Mesna (CAS 19767-45-4), molecular formula C2H5O3S2Na and molecular weight 164.17 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, an ether linkage, Mesna is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 164.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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 Mesna 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.
