Chemical Structure

3-methanesulfonyl-2-methylbutanoic acid CAS 1496436-89-5 chemical structure

Description

The occurrence of 3-methanesulfonyl-2-methylbutanoic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-methanesulfonyl-2-methylbutanoic acid (CAS 1496436-89-5), molecular formula C6H12O4S and molecular weight 180.22 g/mol, is a CATO reference standard with documented purity and traceability.

3-methanesulfonyl-2-methylbutanoic acid (C6H12O4S) 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-methanesulfonyl-2-methylbutanoic acid 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.
