Product Description

Triisopropyl borate TIPB CAS 5419-55-6
Triisopropyl borate (TIPB) is a tertiary borate ester supplied as a clear, moisture-sensitive liquid. It serves as a boron donor and transesterification reagent in organic synthesis, a volatile boron source for catalyst preparation and a precursor in specialty materials and additive syntheses. TIPB is selected where low-residue boron delivery and volatility-assisted removal are advantageous; it requires anhydrous handling and standard solvent controls in production environments.

Applications

  • Boron donor for organoboron chemistry
    Used to introduce boron in the synthesis of boron-containing intermediates, boronic esters and related organoboron reagents.
  • Catalyst precursor & impregnation agent
    Employed to deposit boron on supports or to prepare boron-modified catalysts and ligands via impregnation or vapor-phase routes.
  • Transesterification & ester-exchange reagent
    Used in transesterification steps where isopropoxy boronates are required or as reactive borate esters in specialty syntheses.
  • Precursor for flame-retardant and boron-containing materials
    Serves as a building block in manufacture of boron-containing additives and specialty materials where boron functionality is required.
  • Analytical reagent and R&D
    Supplied for laboratory method development, small-scale synthesis and formulation R&D demanding a volatile boron source.
