Chemical Structure
Description
The occurrence of (Z)-3-((2-(2-Chlorophenyl)hydrazineyl)methylene)-6-methyl-2H-pyran-2,4(3H)-dione 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.
(Z)-3-((2-(2-Chlorophenyl)hydrazineyl)methylene)-6-methyl-2H-pyran-2,4(3H)-dione (CAS 1164458-61-0), molecular formula C13H11ClN2O3 and molecular weight 278.69 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (Z)-3-((2-(2-Chlorophenyl)hydrazineyl)methylene)-6-methyl-2H-pyran-2,4(3H)-dione (C13H11ClN2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
