Enalapril Impurity 14 (Bis(2-chloroethyl)-Butanedioate) CAS 925-17-7

Description

Compared with other compounds in its class, the molecular weight of 243.08 g/mol gives Enalapril Impurity 14 (Bis(2-chloroethyl)-Butanedioate) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Enalapril Impurity 14 (Bis(2-chloroethyl)-Butanedioate) (CAS 925-17-7), a pharmacopoeial impurity reference standard (molecular formula C8H12Cl2O4, MW 243.08 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Enalapril Impurity 14 (Bis(2-chloroethyl)-Butanedioate) (C8H12Cl2O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 243.08 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), Enalapril Impurity 14 (Bis(2-chloroethyl)-Butanedioate) 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.
