Budesonide Impurity 19 (Mixture of Epimer) CAS 192057-49-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Budesonide Impurity 19 (Mixture of Epimer).

CATO supplies Budesonide Impurity 19 (Mixture of Epimer) (CAS 192057-49-1), a pharmacopoeial impurity reference standard (molecular formula C24H32O6, MW 416.51 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C24H32O6, Budesonide Impurity 19 (Mixture of Epimer) contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 416.51 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
