Chemical Structure

Glycerol Impurity 31 CAS CATO-C4X-217131 chemical structure

Description

CATO supplies Glycerol Impurity 31 (CAS CATO-C4X-217131), a pharmacopoeial impurity reference standard (molecular formula C3H10O9P2, MW 252.05 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Glycerol Impurity 31 (C3H10O9P2) is characterized by a phosphate ester group, a carboxylic acid group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
