Chemical Structure

Fludarabine Phosphate EP Impurity B CAS 149297-79-0 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 Fludarabine Phosphate EP Impurity B.

CATO supplies Fludarabine Phosphate EP Impurity B (CAS 149297-79-0), a pharmacopoeial impurity reference standard (molecular formula C5H5N5O, MW 151.13 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amide group, a hydroxyl group, an ether linkage, Fludarabine Phosphate EP Impurity B is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 151.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures Fludarabine Phosphate EP Impurity B under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
