Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-Acetyl-S-(3-carboxy-2-propyl)-L-cysteine Disodium Salt (Mixture of Diastereomers) (CAS 1041285-62-4), molecular formula C9H13NO5SNa and molecular weight 270.25 g/mol, is a CATO reference standard with documented purity and traceability.
N-Acetyl-S-(3-carboxy-2-propyl)-L-cysteine Disodium Salt (Mixture of Diastereomers) (C9H13NO5SNa) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
