Arotinolol Impurity 75 CAS CATO-C4X-185475

Description

The occurrence of Arotinolol Impurity 75 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Arotinolol Impurity 75 (CAS CATO-C4X-185475), a pharmacopoeial impurity reference standard (molecular formula C11H13N3O2S3, MW 315.43 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Arotinolol Impurity 75 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 315.43 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 Arotinolol Impurity 75 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.
