Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 1-Trityl-1H-pyrazole-4-boronic Acid Pinacol Ester is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 436.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
1-Trityl-1H-pyrazole-4-boronic Acid Pinacol Ester (CAS 863238-73-7) is a high-purity analytical reference standard with the molecular formula C28H29BN2O2 and a molecular weight of 436.35 g/mol.
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.
