Chemical Structure
Description
The occurrence of 3-[5-chloro-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl]-N-(3-methylphenyl)acrylamide 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.
3-[5-chloro-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl]-N-(3-methylphenyl)acrylamide (CAS 154563-44-7), molecular formula C12H6ClF4N3O and molecular weight 319.64 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H6ClF4N3O, 3-[5-chloro-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl]-N-(3-methylphenyl)acrylamide 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 319.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 3-[5-chloro-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl]-N-(3-methylphenyl)acrylamide 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.
