Vitamin A EP Impurity A(Kitol) (Mixture of Diastereomers) CAS 22555-09-5

Description

Compared with other compounds in its class, the molecular weight of 572.90 g/mol gives Vitamin A EP Impurity A(Kitol) (Mixture of Diastereomers) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Vitamin A EP Impurity A(Kitol) (Mixture of Diastereomers) (CAS 22555-09-5), a pharmacopoeial impurity reference standard (molecular formula C40H60O2, MW 572.90 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Vitamin A EP Impurity A(Kitol) (Mixture of Diastereomers) (C40H60O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

CATO manufactures Vitamin A EP Impurity A(Kitol) (Mixture of Diastereomers) 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.
