Chemical Structure

3-(4-Fluorophenyl)-1H-pyrazole CAS 154258-82-9 chemical structure

Description

The occurrence of 3-(4-Fluorophenyl)-1H-pyrazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-(4-Fluorophenyl)-1H-pyrazole (CAS 154258-82-9), a certified reference material (molecular formula C9H7FN2, MW 162.16 g/mol) for analytical method development and quality control.

3-(4-Fluorophenyl)-1H-pyrazole (C9H7FN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures 3-(4-Fluorophenyl)-1H-pyrazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
