Chemical Structure
Description
The molecular framework of 1,5-Dimethyl (2E)-3-oxo-2-{2-[2-(trifluoromethyl)phenyl]hydrazin-1-ylidene}pentanedioate (C14H13F3N2O5) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
1,5-Dimethyl (2E)-3-oxo-2-{2-[2-(trifluoromethyl)phenyl]hydrazin-1-ylidene}pentanedioate (CAS 121582-46-5), molecular formula C14H13F3N2O5 and molecular weight 346.26 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
