Vitamin A EP Impurity A (Diels-Alder Dimers) CAS CATO-C4X-177921

Description

The occurrence of Vitamin A EP Impurity A (Diels-Alder Dimers) is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Vitamin A EP Impurity A (Diels-Alder Dimers) (CAS CATO-C4X-177921), a pharmacopoeial impurity reference standard (molecular formula C44H64O4C40H60O2, MW 1229.91 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Vitamin A EP Impurity A (Diels-Alder Dimers) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1229.91 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).

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 (Diels-Alder Dimers) 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.
