Chemical Structure

2,4-Butanesultone CAS 1121-03-5 chemical structure

Description

CATO manufactures 2,4-Butanesultone 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.

CATO supplies 2,4-Butanesultone (CAS 1121-03-5), a certified reference material (molecular formula C4H8O3S, MW 136.17 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 2,4-Butanesultone is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 136.17 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.
