Description

Pinacol Vinylboronate is a high-value organoboron reagent featuring a reactive vinyl group protected by the pinacol ester. This compound matters as a versatile and stable building block for Suzuki-Miyaura cross-coupling reactions, enabling the efficient introduction of a vinyl moiety into complex molecular architectures. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require precise C-C bond formation for synthesizing active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of vinyl-substituted active pharmaceutical ingredients (APIs) and drug candidates via cross-coupling.
• Agrochemical Synthesis: Used in creating novel herbicides, fungicides, and insecticides that incorporate vinyl functional groups.
• Material Science & Polymer Chemistry: Serves as a monomer or functionalization agent in the production of specialty polymers and OLED materials.
• Organic Synthesis & Methodology Development: A crucial reagent in academic and industrial R&D for constructing complex organic molecules and developing new catalytic processes.
• Ligand & Catalyst Preparation: Employed in the synthesis of sophisticated ligands and organometallic catalysts.
• Fine Chemical Production: Integral to the manufacture of high-value flavors, fragrances, and other specialty chemicals.

Quality Control

Our Pinacol Vinylboronate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and GC analysis, to ensure high purity and consistency. Certificates of Analysis (COA) with detailed specifications are provided for every shipment. We adhere to cGMP principles for pharmaceutical-grade material and support compliance with global regulatory standards such as REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) due to its hygroscopic and moisture-sensitive nature. Keep away from heat, sparks, and open flame.
