Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(2-Ethylidenehydrazinyl)-1-methyl-1H-benzo[d]imidazole (CAS 344416-96-2), molecular formula C10H12N4 and molecular weight 188.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(2-Ethylidenehydrazinyl)-1-methyl-1H-benzo[d]imidazole (C10H12N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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.
