Chemical Structure
Description
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.
CATO supplies 1-(2-Hydroxyethyl)-5-methyl-1H-benzo[d]imidazol-2(3H)-one (CAS 63387-92-8), a certified reference material (molecular formula C10H12N2O2, MW 192.21 g/mol) for analytical method development and quality control.
The molecular framework of 1-(2-Hydroxyethyl)-5-methyl-1H-benzo[d]imidazol-2(3H)-one (C10H12N2O2) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
