Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-(-)-Carbidopa-d3 H2O (ring-d3).
(S)-(-)-Carbidopa-d3 H2O (ring-d3) (CAS 1276197-58-0) is a high-purity analytical reference standard with the molecular formula C10H11D3N2O4H2O and a molecular weight of 247.26 g/mol.
(S)-(-)-Carbidopa-d3 H2O (ring-d3) (C10H11D3N2O4H2O) contains deuterium isotope labeling, an amino-acid-derived structure, an amide 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (S)-(-)-Carbidopa-d3 H2O (ring-d3) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
