Chemical Structure

3-(methylsulfonyl)butan-2-one CAS 855280-05-6 chemical structure

Description

CATO supplies 3-(methylsulfonyl)butan-2-one (CAS 855280-05-6), a certified reference material (molecular formula C5H10O3S, MW 150.20 g/mol) for analytical method development and quality control.

3-(methylsulfonyl)butan-2-one (C5H10O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.

As a certified reference material (CRM), 3-(methylsulfonyl)butan-2-one 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.
