Product Name:4-Boronobenzenesulfonic acid
English Name:4-Boronobenzenesulfonic acid
CAS No.:913836-00-7
Aliases:4-Sulfophenylboronic acid, 4-Sulfobenzeneboronic acid
Molecular Formula:C6H7BO5S
Physical Properties:Off-white to light yellow crystalline powder, soluble in water and polar organic solvents (such as methanol, ethanol, DMSO), sparingly soluble in non-polar solvents. Density approximately 1.55 g/cm³ (estimated), melting point above 260°C (decomposition), flash point not applicable. Exhibits dual acidic character of boronic acid and sulfonic acid, with pKa around 8.5 (boronic group) and 1.5 (sulfonic group). Store in a sealed, dry, light-protected environment.
Uses:Used as an organic synthesis intermediate, particularly for constructing biphenyl compounds via Suzuki coupling reactions; also employed in the preparation of sulfonate-functionalized polymers, metal-organic framework materials, and as a synthetic module for introducing boronic acid groups into pharmaceutical molecules; in biomedical fields, it can be used for sensor or labeling reagent synthesis.
Technical Specifications:
Purity: ≥98%
Appearance: off-white to light yellow crystalline powder
Molecular weight: 202.01 g/mol
Melting point: >260°C (decomposition)
Solubility: soluble in water, methanol, ethanol, and DMSO
