Chemical Structure
Description
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.
Chloroquine-d4 Diphosphate Salt (CAS 1246815-14-4) is a high-purity analytical reference standard with the molecular formula C18H22D4ClN3 and a molecular weight of 323.90 g/mol.
The molecular framework of Chloroquine-d4 Diphosphate Salt (C18H22D4ClN3) is characterized by deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
