Chemical Structure
Description
The occurrence of 2-[3-chloro-5-(trifluoromethyl)-2-pyridinyl]-2-(2-thienyl)acetaldehyde 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.
CATO supplies 2-[3-chloro-5-(trifluoromethyl)-2-pyridinyl]-2-(2-thienyl)acetaldehyde oxime (CAS 338770-64-2), a certified reference material (molecular formula C12H8ClF3N2OS, MW 320.72 g/mol) for analytical method development and quality control.
Structurally, 2-[3-chloro-5-(trifluoromethyl)-2-pyridinyl]-2-(2-thienyl)acetaldehyde oxime (C12H8ClF3N2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 320.72 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
