The occurrence of (E)-2-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)-2-(thiophen-2-yl)acetaldehyde O-methyl oxime is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(E)-2-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)-2-(thiophen-2-yl)acetaldehyde O-methyl oxime (CAS 338770-60-8), molecular formula C13H10ClF3N2OS and molecular weight 334.74 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H10ClF3N2OS, (E)-2-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)-2-(thiophen-2-yl)acetaldehyde O-methyl oxime contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 334.74 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
