Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Amino-2-(1H-benzo[d]imidazol-2-yl)phenol (CAS 98792-63-3), molecular formula C13H11N3O and molecular weight 225.25 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-Amino-2-(1H-benzo[d]imidazol-2-yl)phenol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 225.25 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).
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.
