D,L-Cystathionine-d4 CAS 146764-57-0

Description

The occurrence of D,L-Cystathionine-d4 is closely related to deuterium isotope labeling, an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies D,L-Cystathionine-d4 (CAS 146764-57-0), a certified reference material (molecular formula C7H10D4N2O4S, MW 226.29 g/mol) for analytical method development and quality control.

D,L-Cystathionine-d4 (C7H10D4N2O4S) contains deuterium isotope labeling, an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).

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.
