Chemical Structure
Description
(e)-(Ethyl cyano({2-[3-(trifluoromethyl)phenyl]hydrazin-1-ylidene})formate) (CAS 28313-73-7), molecular formula C12H10F3N3O2 and molecular weight 285.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (e)-(Ethyl cyano({2-[3-(trifluoromethyl)phenyl]hydrazin-1-ylidene})formate) (C12H10F3N3O2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
