1-(2-Oxo-2,3-dihydro-1H-benzo[d]imidazol-5-yl)urea CAS 59747-16-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-Oxo-2,3-dihydro-1H-benzo[d]imidazol-5-yl)urea.

CATO supplies 1-(2-Oxo-2,3-dihydro-1H-benzo[d]imidazol-5-yl)urea (CAS 59747-16-9), a certified reference material (molecular formula C8H8N4O2, MW 192.17 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, 1-(2-Oxo-2,3-dihydro-1H-benzo[d]imidazol-5-yl)urea is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.17 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
