Chemical Structure

5,6-Diaminobenzimidazolinone CAS 55621-49-3 chemical structure

Description

CATO supplies 5,6-Diaminobenzimidazolinone (CAS 55621-49-3), a certified reference material (molecular formula C7H8N4O, MW 164.16 g/mol) for analytical method development and quality control.

The molecular framework of 5,6-Diaminobenzimidazolinone (C7H8N4O) is characterized by an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).

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.

CATO manufactures 5,6-Diaminobenzimidazolinone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
