Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(1,1-Dioxo-1,2-thiazolidin-2-yl)-3-methylbutanoic acid.
2-(1,1-Dioxo-1,2-thiazolidin-2-yl)-3-methylbutanoic acid (CAS 1016729-63-7), molecular formula C8H15NO4S and molecular weight 221.27 g/mol, is a CATO reference standard with documented purity and traceability.
2-(1,1-Dioxo-1,2-thiazolidin-2-yl)-3-methylbutanoic acid (C8H15NO4S) contains an amide group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
