Chemical Structure
Description
Propanoic acid, 2-[[(butylthio)thioxomethyl]thio]-2-methyl- (CAS 1146599-39-4), molecular formula C9H16O2S3 and molecular weight 252.42 g/mol, is a CATO reference standard with documented purity and traceability.
Propanoic acid, 2-[[(butylthio)thioxomethyl]thio]-2-methyl- (C9H16O2S3) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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.
