Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 437.97 g/mol gives Hydroxychloroquine-d4 Sulfate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Hydroxychloroquine-d4 Sulfate (CAS 1854126-45-6), molecular formula C18H22D4ClN3OH2O4S and molecular weight 437.97 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Hydroxychloroquine-d4 Sulfate (C18H22D4ClN3OH2O4S) is characterized by deuterium isotope labeling, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures Hydroxychloroquine-d4 Sulfate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
