Chemical Structure
Description
CATO supplies 2,3-Dihydro-1H-benzo[d]imidazole (CAS 4746-67-2), a certified reference material (molecular formula C7H8N2, MW 120.15 g/mol) for analytical method development and quality control.
Owing to a nitrile group, an aromatic ring system, 2,3-Dihydro-1H-benzo[d]imidazole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 120.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
