Chemical Structure

1-(3-Chlorophenyl)-4-(3-(trifluoromethyl)phenyl)-1H-pyrazole CAS 318288-92-5 chemical structure

Description

The occurrence of 1-(3-Chlorophenyl)-4-(3-(trifluoromethyl)phenyl)-1H-pyrazole 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.

1-(3-Chlorophenyl)-4-(3-(trifluoromethyl)phenyl)-1H-pyrazole (CAS 318288-92-5) is a high-purity analytical reference standard with the molecular formula C16H10ClF3N2 and a molecular weight of 322.71 g/mol.

1-(3-Chlorophenyl)-4-(3-(trifluoromethyl)phenyl)-1H-pyrazole (C16H10ClF3N2) 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).

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.
