Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Carbocisteine-13C3 (CAS 1391068-19-1), molecular formula C2[13C]3H9NO4S and molecular weight 182.17 g/mol, is a CATO reference standard with documented purity and traceability.
Carbocisteine-13C3 (C2[13C]3H9NO4S) contains an amide group, a sulfone group, a carboxylic acid 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.
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.
