Chemical Structure
Description
The occurrence of (2E)-4,4,4-trifluoro-1-phenyl-2-(phenylhydrazono)butane-1,3-dione is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2E)-4,4,4-trifluoro-1-phenyl-2-(phenylhydrazono)butane-1,3-dione (CAS 76073-64-8), molecular formula C16H11F3N2O2 and molecular weight 320.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2E)-4,4,4-trifluoro-1-phenyl-2-(phenylhydrazono)butane-1,3-dione (C16H11F3N2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (2E)-4,4,4-trifluoro-1-phenyl-2-(phenylhydrazono)butane-1,3-dione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
