Chemical Structure
Description
The occurrence of 5-(5,6-Dichloro-1-methyl-1H-benzo[d]imidazol-2-yl)pyridin-2(1H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-(5,6-Dichloro-1-methyl-1H-benzo[d]imidazol-2-yl)pyridin-2(1H)-one (CAS 338774-05-3) is a high-purity analytical reference standard with the molecular formula C13H9Cl2N3O and a molecular weight of 294.14 g/mol.
5-(5,6-Dichloro-1-methyl-1H-benzo[d]imidazol-2-yl)pyridin-2(1H)-one (C13H9Cl2N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 5-(5,6-Dichloro-1-methyl-1H-benzo[d]imidazol-2-yl)pyridin-2(1H)-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.
