S-(((R)-2-amino-2-carboxyethyl)thio)-D-cysteine dihydrochloride CAS 13059-63-7

Description

The occurrence of S-(((R)-2-amino-2-carboxyethyl)thio)-D-cysteine dihydrochloride is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

S-(((R)-2-amino-2-carboxyethyl)thio)-D-cysteine dihydrochloride (CAS 13059-63-7), molecular formula C6H12N2O4S2HCl and molecular weight 276.75 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C6H12N2O4S2HCl, S-(((R)-2-amino-2-carboxyethyl)thio)-D-cysteine dihydrochloride contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 276.75 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
