5-Methyl-7-phenyl-6,7-dihydro-1H-1,4-diazepine-2,3-dicarbonitrile CAS 51802-61-0

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 5-Methyl-7-phenyl-6,7-dihydro-1H-1,4-diazepine-2,3-dicarbonitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 236.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

5-Methyl-7-phenyl-6,7-dihydro-1H-1,4-diazepine-2,3-dicarbonitrile (CAS 51802-61-0), molecular formula C14H12N4 and molecular weight 236.27 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
