Chemical Structure

1-Methyl-1H-Pyrazole-4-Boronic Acid CAS 847818-55-7 chemical structure

Description

CATO manufactures 1-Methyl-1H-Pyrazole-4-Boronic Acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

1-Methyl-1H-Pyrazole-4-Boronic Acid (CAS 847818-55-7), molecular formula C4H7BN2O2 and molecular weight 125.92 g/mol, is a CATO reference standard with documented purity and traceability.

1-Methyl-1H-Pyrazole-4-Boronic Acid (C4H7BN2O2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
