1,3-Bis((phenylamino)methyl)-1H-benzo[d]imidazole-2(3H)-thione CAS 33424-75-8

Description

The molecular framework of 1,3-Bis((phenylamino)methyl)-1H-benzo[d]imidazole-2(3H)-thione (C21H20N4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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).

1,3-Bis((phenylamino)methyl)-1H-benzo[d]imidazole-2(3H)-thione (CAS 33424-75-8), molecular formula C21H20N4S and molecular weight 360.48 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.

As a certified reference material (CRM), 1,3-Bis((phenylamino)methyl)-1H-benzo[d]imidazole-2(3H)-thione 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.
