Chemical Structure

Enzalutamide Impurity 33 CAS 934600-95-0 chemical structure

Description

The occurrence of Enzalutamide Impurity 33 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Enzalutamide Impurity 33 (CAS 934600-95-0), a pharmacopoeial impurity reference standard (molecular formula C8H7F3N2O, MW 204.15 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Enzalutamide Impurity 33 (C8H7F3N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 204.15 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

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.
