Ibuprofen EP Impurity Q CAS 36039-35-7 chemical structure

Description

CATO supplies Ibuprofen EP Impurity Q (CAS 36039-35-7), a pharmacopoeial impurity reference standard (molecular formula C12H18O, MW 178.27 g/mol) used for the identification and quantification of trace impurities in APIs.

Ibuprofen EP Impurity Q (C12H18O) contains a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Ibuprofen EP Impurity Q 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.
