Chemical Structure

2-Methyl-2-propene-1-sulfonate sodium salt CAS 1561-92-8 chemical structure

Description

The occurrence of 2-Methyl-2-propene-1-sulfonate sodium salt 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.

2-Methyl-2-propene-1-sulfonate sodium salt (CAS 1561-92-8), molecular formula C4H7O3SNa and molecular weight 158.15 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 2-Methyl-2-propene-1-sulfonate sodium salt is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 158.15 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.

As a certified reference material (CRM), 2-Methyl-2-propene-1-sulfonate sodium salt 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.
