2-Cyanophenothiazine Impurity 2 CAS CATO-C4X-29072

Description

Compared with other compounds in its class, the molecular weight of 446.55 g/mol gives 2-Cyanophenothiazine Impurity 2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Cyanophenothiazine Impurity 2 (CAS CATO-C4X-29072) is a certified pharmaceutical impurity reference standard with the molecular formula C26H14N4S2 and a molecular weight of 446.55 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 2-Cyanophenothiazine Impurity 2 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 446.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 2-Cyanophenothiazine Impurity 2 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.
