4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1-(1-(2-(trifluoromethyl)-phenyl)ethyl)-1H-pyrazole CAS 1604036-77-2

Description

The molecular framework of 4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1-(1-(2-(trifluoromethyl)-phenyl)ethyl)-1H-pyrazole (C18H22BF3N2O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).

4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1-(1-(2-(trifluoromethyl)-phenyl)ethyl)-1H-pyrazole (CAS 1604036-77-2), molecular formula C18H22BF3N2O2 and molecular weight 366.19 g/mol, is a CATO reference standard with documented purity and traceability.

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.
