Description

Ethyldichloroborane CAS NO 1739-53-3 is a highly reactive organoboron compound primarily used as a versatile reagent in synthetic organic chemistry. Its value lies in its ability to act as a powerful electrophilic boron source and a precursor for the synthesis of complex boron-containing molecules. This chemical is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, particularly for hydroboration reactions and the development of novel boron-based catalysts and polymers.

Application

• Hydroboration Reagent: A key electrophile for the hydroboration of alkenes and alkynes, forming organoboranes for subsequent cross-coupling reactions.
• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and complex molecules requiring selective boron functionalization.
• Polymer & Material Science: Serves as a precursor for boron-containing polymers, resins, and advanced ceramic materials.
• Agrochemical Synthesis: Employed in creating novel herbicides, fungicides, and plant growth regulators with boron-based active centers.
• Catalyst Preparation: A starting material for synthesizing Lewis acid catalysts and co-catalysts used in organic transformations.
• Organic Synthesis Building Block: Facilitates the introduction of the ethylboron moiety into target molecules for further functionalization.
• Laboratory Research: A critical reagent for methodological development in academic and industrial R&D laboratories focusing on organometallic chemistry.

Quality Control

Our Ethyldichloroborane is produced and handled under stringent quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis, including assay by titration and impurity profiling via GC or NMR. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, well-ventilated area, away from heat, moisture, and incompatible materials such as strong bases and oxidizing agents. Due to its highly volatile and moisture-sensitive nature, containers must be kept sealed and handled under anhydrous conditions.
