Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (3E)-3-[2-(4-Chlorophenyl)hydrazin-1-ylidene]-1-methyl-2,3-dihydro-1H-indol-2-one (CAS 113258-69-8), a certified reference material (molecular formula C15H12ClN3O, MW 285.73 g/mol) for analytical method development and quality control.
(3E)-3-[2-(4-Chlorophenyl)hydrazin-1-ylidene]-1-methyl-2,3-dihydro-1H-indol-2-one (C15H12ClN3O) 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.
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.
