Beclometasone Dipropionate Monohydrate EP Impurity C CAS CATO-C4X-14743 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 Beclometasone Dipropionate Monohydrate EP Impurity C.

CATO supplies Beclometasone Dipropionate Monohydrate EP Impurity C (CAS CATO-C4X-14743), a pharmacopoeial impurity reference standard (molecular formula C29H39ClO7, MW 535.07 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C29H39ClO7, Beclometasone Dipropionate Monohydrate EP Impurity C contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 535.07 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
