Chemical Structure
Description
2-((3,4,4-Trifluorobut-3-en-1-yl)thio)nicotinohydrazide (CAS 478247-67-5), molecular formula C10H10F3N3OS and molecular weight 277.27 g/mol, is a CATO reference standard with documented purity and traceability.
2-((3,4,4-Trifluorobut-3-en-1-yl)thio)nicotinohydrazide (C10H10F3N3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
