(1H-Benzo[d]imidazol-1-yl)phosphonic acid (CAS 93755-82-9), molecular formula C7H7N2O3P and molecular weight 198.12 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (1H-Benzo[d]imidazol-1-yl)phosphonic acid (C7H7N2O3P) is characterized by an amide group, a phosphonate group, a carboxylic acid 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.
