Chemical Structure
Description
The occurrence of (E)-2-(2-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)hydrazono)-1-(pyridin-2-yl)ethan-1-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(E)-2-(2-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)hydrazono)-1-(pyridin-2-yl)ethan-1-one (CAS 400074-11-5) is a high-purity analytical reference standard with the molecular formula C13H8ClF3N4O and a molecular weight of 328.68 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, (E)-2-(2-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)hydrazono)-1-(pyridin-2-yl)ethan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 328.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
