Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Flurbiprofen Impurity 42 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
CATO supplies Flurbiprofen Impurity 42 (CAS CATO-C4X-144442), a pharmacopoeial impurity reference standard (molecular formula C8H14O4, MW 174.19 g/mol) used for the identification and quantification of trace impurities in APIs.
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.
CATO manufactures Flurbiprofen Impurity 42 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.
