The occurrence of 1,4-Butanesultone 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.
1,4-Butanesultone (CAS 1633-83-6), molecular formula C4H8O3S and molecular weight 136.17 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, 1,4-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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
