Vitamin A EP Impurity A(Kitol Diacetate) (Mixture of Diastereomers) CAS 13828-13-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Vitamin A EP Impurity A(Kitol Diacetate) (Mixture of Diastereomers).

CATO supplies Vitamin A EP Impurity A(Kitol Diacetate) (Mixture of Diastereomers) (CAS 13828-13-2), a pharmacopoeial impurity reference standard (molecular formula C44H64O4, MW 656.98 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C44H64O4, Vitamin A EP Impurity A(Kitol Diacetate) (Mixture of Diastereomers) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 656.98 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO manufactures Vitamin A EP Impurity A(Kitol Diacetate) (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.
