Chemical Structure
Description
The occurrence of 2-[2-(3,5-Dichlorophenyl)hydrazono]-3-(4-methylphenyl)-3-oxopropanal oxime 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.
2-[2-(3,5-Dichlorophenyl)hydrazono]-3-(4-methylphenyl)-3-oxopropanal oxime (CAS 338414-24-7), molecular formula C16H13Cl2N3O2 and molecular weight 350.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-[2-(3,5-Dichlorophenyl)hydrazono]-3-(4-methylphenyl)-3-oxopropanal oxime (C16H13Cl2N3O2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 2-[2-(3,5-Dichlorophenyl)hydrazono]-3-(4-methylphenyl)-3-oxopropanal oxime under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
