Chemical Structure

Paroxetine-d4 HCl CAS 1217683-35-6 chemical structure

Description

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.

Paroxetine-d4 HCl (CAS 1217683-35-6), molecular formula C19H16D4FNO3HCl and molecular weight 369.85 g/mol, is a CATO reference standard with documented purity and traceability.

Paroxetine-d4 HCl (C19H16D4FNO3HCl) contains deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.

CATO manufactures Paroxetine-d4 HCl 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.
