Chemical Structure

Riluzole impurity 19 CAS 2995-45-1 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 Riluzole impurity 19.

CATO supplies Riluzole impurity 19 (CAS 2995-45-1), a pharmacopoeial impurity reference standard (molecular formula C7H4F3NO3, MW 207.11 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, Riluzole impurity 19 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 207.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 Riluzole impurity 19 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.
