Chemical Structure
Description
4-(Methyldisulfanyl)butanoic acid (CAS 138148-60-4), molecular formula C5H10O2S2 and molecular weight 166.26 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, 4-(Methyldisulfanyl)butanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.26 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.
