1-(2-Bromo-1,1,2,2-tetrafluoroethyl)-3,5-dimethyl-1H-pyrazole CAS 1125518-67-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 275.04 g/mol gives 1-(2-Bromo-1,1,2,2-tetrafluoroethyl)-3,5-dimethyl-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(2-Bromo-1,1,2,2-tetrafluoroethyl)-3,5-dimethyl-1H-pyrazole (CAS 1125518-67-3) is a high-purity analytical reference standard with the molecular formula C7H7BrF4N2 and a molecular weight of 275.04 g/mol.

The molecular framework of 1-(2-Bromo-1,1,2,2-tetrafluoroethyl)-3,5-dimethyl-1H-pyrazole (C7H7BrF4N2) is characterized by a nitrile group, fluorine/bromine 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.

CATO manufactures 1-(2-Bromo-1,1,2,2-tetrafluoroethyl)-3,5-dimethyl-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.
