Chemical Structure
Description
7,9-Dichloro-1-methyl-1,2,3,4-tetrahydro-5H-benzo[e][1,4]diazepin-5-one (CAS 62675-32-5), molecular formula C10H10Cl2N2O and molecular weight 245.11 g/mol, is a CATO reference standard with documented purity and traceability.
7,9-Dichloro-1-methyl-1,2,3,4-tetrahydro-5H-benzo[e][1,4]diazepin-5-one (C10H10Cl2N2O) 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 7,9-Dichloro-1-methyl-1,2,3,4-tetrahydro-5H-benzo[e][1,4]diazepin-5-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.
