Chemical Structure

4-Phenyl-1H-benzo[b][1,4]diazepin-2(3H)-one CAS 16439-95-5 chemical structure

Description

4-Phenyl-1H-benzo[b][1,4]diazepin-2(3H)-one (CAS 16439-95-5) is a high-purity analytical reference standard with the molecular formula C15H12N2O and a molecular weight of 236.27 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-Phenyl-1H-benzo[b][1,4]diazepin-2(3H)-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 236.27 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 4-Phenyl-1H-benzo[b][1,4]diazepin-2(3H)-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.
