BPA Impurity 5 CAS CATO-C4X-31395 chemical structure

Description

As a certified reference material (CRM), BPA Impurity 5 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies BPA Impurity 5 (CAS CATO-C4X-31395), a pharmacopoeial impurity reference standard (molecular formula C19H30BNO4, MW 347.26 g/mol) used for the identification and quantification of trace impurities in APIs.

BPA Impurity 5 (C19H30BNO4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
