(4-(1-Benzyl-1H-pyrazol-4-yl)phenyl)boronic acid CAS 1191061-96-7

Description

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.

(4-(1-Benzyl-1H-pyrazol-4-yl)phenyl)boronic acid (CAS 1191061-96-7), molecular formula C16H15BN2O2 and molecular weight 278.11 g/mol, is a CATO reference standard with documented purity and traceability.

(4-(1-Benzyl-1H-pyrazol-4-yl)phenyl)boronic acid (C16H15BN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
