2,3-Dihydro-1H-benzo[d]imidazole-5-carboxylic acid CAS 851669-20-0

Description

As a certified reference material (CRM), 2,3-Dihydro-1H-benzo[d]imidazole-5-carboxylic acid 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.

CATO supplies 2,3-Dihydro-1H-benzo[d]imidazole-5-carboxylic acid (CAS 851669-20-0), a certified reference material (molecular formula C8H8N2O2, MW 164.16 g/mol) for analytical method development and quality control.

The molecular framework of 2,3-Dihydro-1H-benzo[d]imidazole-5-carboxylic acid (C8H8N2O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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.
