Chemical Structure
Description
The occurrence of 4-(2-(4-Chlorobenzoyl)hydrazinyl)-4-oxobutanoic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(2-(4-Chlorobenzoyl)hydrazinyl)-4-oxobutanoic acid (CAS 215121-50-9) is a high-purity analytical reference standard with the molecular formula C11H11ClN2O4 and a molecular weight of 270.67 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 4-(2-(4-Chlorobenzoyl)hydrazinyl)-4-oxobutanoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 270.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
