Chemical Structure
Description
7-Chloro-5-(2-chlorophenyl)-2-hydrazinyl-3H-1,4-benzodiazepine (1.0mg/ml in Acetonitrile) (CAS 40070-48-2), molecular formula C15H12Cl2N4 and molecular weight 319.19 g/mol, is a CATO reference standard with documented purity and traceability.
7-Chloro-5-(2-chlorophenyl)-2-hydrazinyl-3H-1,4-benzodiazepine (1.0mg/ml in Acetonitrile) (C15H12Cl2N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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. 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.
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.
