Chemical Structure

Dexlansoprazole Impurity 50 CAS 87-91-2 chemical structure

Description

The molecular framework of Dexlansoprazole Impurity 50 (C8H14O6) is characterized by a carboxylic acid group, a hydroxyl 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.

CATO supplies Dexlansoprazole Impurity 50 (CAS 87-91-2), a pharmacopoeial impurity reference standard (molecular formula C8H14O6, MW 206.19 g/mol) used for the identification and quantification of trace impurities in APIs.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

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.
