Chemical Structure

Quetiapine-d8 Hemifumarate CAS 1435938-24-1 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.

Quetiapine-d8 Hemifumarate (CAS 1435938-24-1), molecular formula C21H17D8N3O2SC4H4O4 and molecular weight 507.63 g/mol, is a CATO reference standard with documented purity and traceability.

Quetiapine-d8 Hemifumarate (C21H17D8N3O2SC4H4O4) contains deuterium isotope labeling, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
