Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 327.69 g/mol gives (E)-2-(2-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)hydrazono)-1-phenylethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(E)-2-(2-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)hydrazono)-1-phenylethan-1-one (CAS 339099-97-7), molecular formula C14H9ClF3N3O and molecular weight 327.69 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (E)-2-(2-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)hydrazono)-1-phenylethan-1-one (C14H9ClF3N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 (E)-2-(2-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)hydrazono)-1-phenylethan-1-one 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.
