Orlistat impurity 41 CAS 68659-61-0 chemical structure

Description

CATO manufactures Orlistat impurity 41 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.

CATO supplies Orlistat impurity 41 (CAS 68659-61-0), a pharmacopoeial impurity reference standard (molecular formula C19H19P, MW 278.33 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to organophosphorus functionality, a polycyclic aromatic system, Orlistat impurity 41 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 278.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
