Chemical Structure

Roxatidine impurity 72 CAS CATO-C4X-121372 chemical structure

Description

The occurrence of Roxatidine impurity 72 is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Roxatidine impurity 72 (CAS CATO-C4X-121372) is a certified pharmaceutical impurity reference standard with the molecular formula C5H8O5 and a molecular weight of 148.11 g/mol.

The molecular framework of Roxatidine impurity 72 (C5H8O5) is characterized by a carbohydrate-derived structure. 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.
