Chemical Structure
Description
CATO supplies 1-Isopentyl-3-(trifluoromethyl)pyrazole-4-boronic acid (CAS 2377609-86-2), a certified reference material (molecular formula C9H14BF3N2O2, MW 250.03 g/mol) for analytical method development and quality control.
The molecular framework of 1-Isopentyl-3-(trifluoromethyl)pyrazole-4-boronic acid (C9H14BF3N2O2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
