Description
As a certified reference material (CRM), Hydroxychloroquine-d4 Sulfate 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.
Hydroxychloroquine-d4 Sulfate (CAS 1216432-56-2) is a high-purity analytical reference standard with the molecular formula C18H22D4ClN3OH2O4S and a molecular weight of 437.97 g/mol.
Hydroxychloroquine-d4 Sulfate (C18H22D4ClN3OH2O4S) contains deuterium isotope labeling, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
