(3Z)-3-(hydroxyimino)-1-phenyl-2,3-dihydro-1H-indol-2-one 28150-90-5 9L-302S CAS 28150-90-5 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-(hydroxyimino)-1-phenyl-2,3-dihydro-1H-indol-2-one 28150-90-5 9L-302S.

(3Z)-3-(hydroxyimino)-1-phenyl-2,3-dihydro-1H-indol-2-one 28150-90-5 9L-302S (CAS 28150-90-5) is a high-purity analytical reference standard with the molecular formula C14H10N2O2 and a molecular weight of 238.24 g/mol.

(3Z)-3-(hydroxyimino)-1-phenyl-2,3-dihydro-1H-indol-2-one 28150-90-5 9L-302S (C14H10N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
