Bexarotene Impurity 4 CAS 29641-87-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Bexarotene Impurity 4.

CATO supplies Bexarotene Impurity 4 (CAS 29641-87-0), a pharmacopoeial impurity reference standard (molecular formula C15H22, MW 202.34 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C15H22, Bexarotene Impurity 4 contains an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 202.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Bexarotene Impurity 4 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
