Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3Z)-3-[(4-Chlorophenyl)imino]-1-phenyl-2,3-dihydro-1H-indol-2-one.
CATO supplies (3Z)-3-[(4-Chlorophenyl)imino]-1-phenyl-2,3-dihydro-1H-indol-2-one (CAS 303149-12-4), a certified reference material (molecular formula C20H13ClN2O, MW 332.78 g/mol) for analytical method development and quality control.
Structurally, (3Z)-3-[(4-Chlorophenyl)imino]-1-phenyl-2,3-dihydro-1H-indol-2-one (C20H13ClN2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 332.78 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
