Chemical Structure

Imrecoxib Impurity 9 CAS 3038592-01-4 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 Imrecoxib Impurity 9.

CATO supplies Imrecoxib Impurity 9 (CAS 3038592-01-4), a pharmacopoeial impurity reference standard (molecular formula C21H21NO4S, MW 383.46 g/mol) used for the identification and quantification of trace impurities in APIs.

Imrecoxib Impurity 9 (C21H21NO4S) contains a flavonoid core, an amide group, a sulfone 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), Imrecoxib Impurity 9 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.
