Chemical Structure
Description
The occurrence of 2-(4-Chloro-1h-pyrazol-1-yl)-5-(trifluoromethyl)aniline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(4-Chloro-1h-pyrazol-1-yl)-5-(trifluoromethyl)aniline (CAS 1006322-99-1), molecular formula C10H7ClF3N3 and molecular weight 261.63 g/mol, is a CATO reference standard with documented purity and traceability.
2-(4-Chloro-1h-pyrazol-1-yl)-5-(trifluoromethyl)aniline (C10H7ClF3N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
