Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2-Oxo-2,3-dihydro-1H-benzo[d]imidazol-5-yl)boronic acid.
CATO supplies (2-Oxo-2,3-dihydro-1H-benzo[d]imidazol-5-yl)boronic acid (CAS 1194483-04-9), a certified reference material (molecular formula C7H7BN2O3, MW 177.95 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (2-Oxo-2,3-dihydro-1H-benzo[d]imidazol-5-yl)boronic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 177.95 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 (2-Oxo-2,3-dihydro-1H-benzo[d]imidazol-5-yl)boronic acid 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.
