Chemical Structure

Quetiapine impurity 83 CAS 2101854-40-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Quetiapine impurity 83.

CATO supplies Quetiapine impurity 83 (CAS 2101854-40-2), a pharmacopoeial impurity reference standard (molecular formula C13H10N2OS, MW 242.30 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, Quetiapine impurity 83 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 242.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures Quetiapine impurity 83 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.
