Chemical Structure
Description
The occurrence of N-[2-(1,3-Dimethyl-4-nitro-1H-pyrazol-5-yl)vinyl]-4-(trifluoromethoxy)aniline is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-[2-(1,3-Dimethyl-4-nitro-1H-pyrazol-5-yl)vinyl]-4-(trifluoromethoxy)aniline (CAS 436100-82-2), molecular formula C14H13F3N4O3 and molecular weight 342.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-[2-(1,3-Dimethyl-4-nitro-1H-pyrazol-5-yl)vinyl]-4-(trifluoromethoxy)aniline (C14H13F3N4O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), N-[2-(1,3-Dimethyl-4-nitro-1H-pyrazol-5-yl)vinyl]-4-(trifluoromethoxy)aniline 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.
