Chemical Structure

Indobufen Impurity 30 CAS CATO-C4X-179230 chemical structure

Description

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 supplies Indobufen Impurity 30 (CAS CATO-C4X-179230), a pharmacopoeial impurity reference standard (molecular formula C20H22N2O4, MW 354.40 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Indobufen Impurity 30 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 354.40 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.

As a certified reference material (CRM), Indobufen Impurity 30 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.
