Chemical Structure
Description
The occurrence of 2-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-2-(3-chlorophenyl)acetamide 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.
2-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-2-(3-chlorophenyl)acetamide (CAS 338407-76-4), molecular formula C14H9Cl2F3N2O and molecular weight 349.14 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H9Cl2F3N2O, 2-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-2-(3-chlorophenyl)acetamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 349.14 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).
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.
As a certified reference material (CRM), 2-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-2-(3-chlorophenyl)acetamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
