Description

2,2-Dimethylpropyltrifluoroborate Potassium Salt is a high-purity organoboron reagent, specifically a potassium trifluoroborate salt, valued for its enhanced stability and handling properties compared to boronic acids. This compound serves as a critical coupling partner in Suzuki-Miyaura cross-coupling reactions, a cornerstone methodology for constructing carbon-carbon bonds in complex molecule synthesis. It is essential for researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, shelf-stable building blocks for drug discovery and fine chemical production. The product is identified by CAS NO 1150655-02-9.

Application

• Pharmaceutical Intermediate Synthesis: A key building block in the synthesis of active pharmaceutical ingredients (APIs) via palladium-catalyzed cross-coupling reactions.
• Agrochemical Development: Used in creating novel herbicides, fungicides, and insecticides by enabling the introduction of the 2,2-dimethylpropyl (neopentyl) moiety.
• Material Science Research: Employed in the development of organic electronic materials, such as polymers and small molecules for OLEDs or OFETs.
• Ligand and Catalyst Preparation: Serves as a precursor for synthesizing specialized ligands and organometallic catalysts.
• Chemical Biology & Probe Development: Utilized in the labeling and modification of biomolecules for diagnostic and research applications.
• Fine Chemical and Flavor/Fragrance Synthesis: Facilitates the production of complex, high-value specialty chemicals.

Quality Control

Our 2,2-Dimethylpropyltrifluoroborate Potassium Salt is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (¹H, ¹³C, ¹¹B, ¹⁹F) for structural confirmation and HPLC or titration for purity assessment, to ensure compliance with stringent specifications. Certificates of Analysis (COA) detailing all test results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) in a desiccator for long-term storage to maintain stability and purity.
