Chemical Structure

3-Trifluoromethyl-1<I>H</I>-pyrazole-4-boronic acid pinacol ester CAS 1218790-40-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 266.07 g/mol gives 3-Trifluoromethyl-1<I>H</I>-pyrazole-4-boronic acid pinacol ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Trifluoromethyl-1<I>H</I>-pyrazole-4-boronic acid pinacol ester (CAS 1218790-40-9) is a high-purity analytical reference standard with the molecular formula C10H18BF3N2O2 and a molecular weight of 266.07 g/mol.

The molecular framework of 3-Trifluoromethyl-1<I>H</I>-pyrazole-4-boronic acid pinacol ester (C10H18BF3N2O2) 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 its high hydrophobicity (logP), 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
