Chemical Structure

Haloperidol Impurity 17 CAS 63843-83-4 chemical structure

Description

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 supplies Haloperidol Impurity 17 (CAS 63843-83-4), a pharmacopoeial impurity reference standard (molecular formula C18H21NO, MW 267.37 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Haloperidol Impurity 17 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 267.37 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).

CATO manufactures Haloperidol Impurity 17 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.
