Chemical Structure
Description
The molecular framework of Quetiapine-d4 Hemifumarate (C21H21D4N3O2SC4H4O4) is characterized by deuterium isotope labeling, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO supplies Quetiapine-d4 Hemifumarate (CAS 1217310-65-0), a certified reference material (molecular formula C21H21D4N3O2SC4H4O4, MW 503.61 g/mol) for analytical method development and quality control.
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.
