Description

Ethyl Borate is a versatile organoboron compound primarily used as a reagent and intermediate in advanced chemical synthesis. Its significance lies in its ability to act as a source of boron and ethoxy groups, facilitating critical reactions in the production of fine chemicals and materials. This product is essential for R&D laboratories and industrial manufacturers in the pharmaceutical, agrochemical, and specialty polymer sectors. CAS NO 34099-73-5.

Application

• Key intermediate in the synthesis of pharmaceutical active ingredients and boron-containing drug candidates.
• Precursor for the preparation of boron esters and other organoboron reagents used in cross-coupling reactions (e.g., Suzuki-Miyaura).
• Catalyst or co-catalyst component in polymerization reactions and resin formulations.
• Starting material for the production of flame retardants and specialty additives for polymers.
• Reagent in organic synthesis for transesterification and alkoxylation reactions.
• Used in the manufacture of semiconductors and electronic chemicals as a dopant source or CVD/ALD precursor.
• Intermediate in the synthesis of agrochemicals, such as herbicides and fungicides.
• Research and development applications in material science and coordination chemistry.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from heat, sparks, and open flame.
