Chemical Structure

Opicapone impurity 30 CAS CATO-C4X-240430 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 382.20 g/mol gives Opicapone impurity 30 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Opicapone impurity 30 (CAS CATO-C4X-240430), a pharmacopoeial impurity reference standard (molecular formula C16H13Cl2N3O4, MW 382.20 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Opicapone impurity 30 (C16H13Cl2N3O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 382.20 g/mol, it falls into the moderately-high-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
