Description
Compared with other compounds in its class, the molecular weight of 308.13 g/mol gives 6-Chloro-3-[(3-chloro-2-fluorophenyl)methylene]-1,3-dihydro-2H-indol-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
6-Chloro-3-[(3-chloro-2-fluorophenyl)methylene]-1,3-dihydro-2H-indol-2-one (CAS 897365-76-3) is a high-purity analytical reference standard with the molecular formula C15H8Cl2FNO and a molecular weight of 308.13 g/mol.
6-Chloro-3-[(3-chloro-2-fluorophenyl)methylene]-1,3-dihydro-2H-indol-2-one (C15H8Cl2FNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/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.
