Chemical Structure

Topiramate EP Impurity E (D-fructopyranose) CAS 6347-01-9 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 Topiramate EP Impurity E (D-fructopyranose).

CATO supplies Topiramate EP Impurity E (D-fructopyranose) (CAS 6347-01-9), a pharmacopoeial impurity reference standard (molecular formula C6H12O6, MW 180.16 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a carbohydrate-derived structure, Topiramate EP Impurity E (D-fructopyranose) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 180.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
