Description

Diethylborinic Acid 1-Methyl-2-Propynyl Ester is a specialized organoboron compound that serves as a versatile reagent in advanced synthetic chemistry. Its primary value lies in its role as a boron source and a key intermediate for constructing complex molecular architectures, particularly in the development of pharmaceuticals and functional materials. This product is essential for research chemists and process development scientists in the pharmaceutical, agrochemical, and materials science industries who require high-purity, reactive boron intermediates.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly those containing boron for boron neutron capture therapy (BNCT) or as enzyme inhibitors.
• Agrochemical Synthesis: Used in the research and development of new pesticides and herbicides, where the boron moiety can impart unique biological activity.
• Polymer & Materials Science: Acts as a monomer or cross-linking agent in the production of specialty polymers, resins, and advanced materials with tailored thermal or mechanical properties.
• Organic Synthesis Reagent: Employed in Suzuki-Miyaura and other palladium-catalyzed cross-coupling reactions to introduce alkyl or other functional groups.
• Catalyst & Ligand Precursor: Serves as a precursor for generating novel catalysts or ligands used in asymmetric synthesis and homogeneous catalysis.
• Research & Development: A critical tool in academic and industrial R&D laboratories for exploring new synthetic methodologies and reaction pathways involving organoboron chemistry.

Quality Control

Our Diethylborinic Acid 1-Methyl-2-Propynyl Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, GC, and titration methods, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory 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, and well-ventilated place. Recommended storage temperature is 2-8°C for long-term stability. Due to its moisture-sensitive and easily oxidized nature, containers must be kept sealed and handled under an inert environment to prevent degradation.
