Overview
Tributyl borate丨CAS 688-74-4 is an organoboron compound that appears as a clear, colorless liquid with a mild odor. As a trialkyl borate ester, it is widely used in chemical synthesis, catalysis, and as a boron source in various applications.
Applications
1. Reagent in Organic Synthesis
Tributyl borate丨CAS 688-74-4 is used in organic reactions as a mild borating reagent.
It participates in the preparation of boronic acids, boronate esters, and organoboron intermediates used in Suzuki–Miyaura cross-coupling.
It can act as a boron source in complex molecule synthesis, particularly in pharmaceutical and agrochemical manufacturing.
2. Boron Source for Flame Retardants
Acts as a boron donor in formulations for flame retardants in plastics, textiles, and cellulose-based materials.
Boron compounds suppress combustion by forming a protective layer and inhibiting radical propagation.
3. Additive in Lubricants and Greases
Used as an additive in high-performance lubricants and greases.
Improves thermal stability, load-carrying capacity, and anti-wear properties.
4. Solvent and Plasticizer Intermediate
Serves as a plasticizer and solvent in the formulation of resins, coatings, and adhesives.
Can modify viscosity, flexibility, and film-forming properties in polymer systems.
5. Intermediate in Borosilicate Glass and Ceramics
Used as a precursor in the production of borosilicate glasses, enamels, and ceramic glazes.
Enhances thermal shock resistance, optical clarity, and chemical durability of glass.
6. Catalytic and Analytical Chemistry
Employed in catalysis research, particularly in reactions involving boron–oxygen bond transformations.
Utilized in analytical chemistry for complexation reactions and as a reagent for specific detection protocols.
