Chemical Structure
Description
The occurrence of Chloroquine-d5 Diphosphate is closely related to deuterium isotope labeling, a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Chloroquine-d5 Diphosphate (CAS 50-63-5 (unlabelled)), molecular formula C18H21D5ClN3H3O4P and molecular weight 422.90 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Chloroquine-d5 Diphosphate (C18H21D5ClN3H3O4P) contains deuterium isotope labeling, a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 422.90 g/mol, it falls into the moderately-high-molecular-weight range. 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.
As a certified reference material (CRM), Chloroquine-d5 Diphosphate 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.
