1-(4-Chlorophenyl)-1,3-dihydro-2H-benzo[d]imidazol-2-one CAS 19920-11-7 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 1-(4-Chlorophenyl)-1,3-dihydro-2H-benzo[d]imidazol-2-one.

1-(4-Chlorophenyl)-1,3-dihydro-2H-benzo[d]imidazol-2-one (CAS 19920-11-7) is a high-purity analytical reference standard with the molecular formula C13H9ClN2O and a molecular weight of 244.68 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1-(4-Chlorophenyl)-1,3-dihydro-2H-benzo[d]imidazol-2-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 244.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 1-(4-Chlorophenyl)-1,3-dihydro-2H-benzo[d]imidazol-2-one 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.
