Description

Compared with other compounds in its class, the molecular weight of 189.97 g/mol gives (2-(1H-pyrazol-1-yl)pyrimidin-5-yl)boronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(2-(1H-pyrazol-1-yl)pyrimidin-5-yl)boronic acid (CAS 1644061-13-1), molecular formula C7H7BN4O2 and molecular weight 189.97 g/mol, is a CATO reference standard with documented purity and traceability.

(2-(1H-pyrazol-1-yl)pyrimidin-5-yl)boronic acid (C7H7BN4O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
