Chemical Structure

Potassium 1H-pyrazole-4-trifluoroborate CAS 1111732-81-0 chemical structure

Description

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.

Potassium 1H-pyrazole-4-trifluoroborate (CAS 1111732-81-0) is a high-purity analytical reference standard with the molecular formula C3H3BF3N2K and a molecular weight of 173.97 g/mol.

The molecular framework of Potassium 1H-pyrazole-4-trifluoroborate (C3H3BF3N2K) is characterized by a nitrile group, 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.

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.
