Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1 - Benzyl - 1H - pyrazole - 4 - boronic acid 1-(phenylmethyl)-1h-pyrazole-4-boronic acid, 1-benzyl-4-borono-1h-pyrazole 1-Benzyl-4-1H-pyrazoleboronic acid 1-benzyl-1H-pyrazol-4-ylboronic acid 1-benzyl-1h-pyrazol-4-boronic acid 1-benzyl-1h-pyrazole-4-boronic acid 1h-pyrazole-1-benzyl-4-boronic acid 1h-pyrazole-benzyl-4-boronic acid 852362-22-2 akos brn-0254 boronic acid, [1-(phenylmethyl)-1H-pyrazol-4-yl]-.

1 - Benzyl - 1H - pyrazole - 4 - boronic acid 1-(phenylmethyl)-1h-pyrazole-4-boronic acid, 1-benzyl-4-borono-1h-pyrazole 1-Benzyl-4-1H-pyrazoleboronic acid 1-benzyl-1H-pyrazol-4-ylboronic acid 1-benzyl-1h-pyrazol-4-boronic acid 1-benzyl-1h-pyrazole-4-boronic acid 1h-pyrazole-1-benzyl-4-boronic acid 1h-pyrazole-benzyl-4-boronic acid 852362-22-2 akos brn-0254 boronic acid, [1-(phenylmethyl)-1H-pyrazol-4-yl]- (CAS 852362-22-2) is a high-purity analytical reference standard with the molecular formula C10H11BN2O2 and a molecular weight of 202.02 g/mol.

The molecular framework of 1 - Benzyl - 1H - pyrazole - 4 - boronic acid 1-(phenylmethyl)-1h-pyrazole-4-boronic acid, 1-benzyl-4-borono-1h-pyrazole 1-Benzyl-4-1H-pyrazoleboronic acid 1-benzyl-1H-pyrazol-4-ylboronic acid 1-benzyl-1h-pyrazol-4-boronic acid 1-benzyl-1h-pyrazole-4-boronic acid 1h-pyrazole-1-benzyl-4-boronic acid 1h-pyrazole-benzyl-4-boronic acid 852362-22-2 akos brn-0254 boronic acid, [1-(phenylmethyl)-1H-pyrazol-4-yl]- (C10H11BN2O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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).

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.
