Desoximetasone Impurity 5 CAS 4306-57-4

Description

Compared with other compounds in its class, the molecular weight of 392.92 g/mol gives Desoximetasone Impurity 5 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Desoximetasone Impurity 5 (CAS 4306-57-4), a pharmacopoeial impurity reference standard (molecular formula C22H29ClO4, MW 392.92 g/mol) used for the identification and quantification of trace impurities in APIs.

Desoximetasone Impurity 5 (C22H29ClO4) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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), Desoximetasone 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.
