Description

9-Octadecenoic Acid (Z)-, (2-Hydroxy-1,3,2-Dioxaborolan-4-Yl)Methylester is a specialized oleic acid derivative containing a boronate ester functional group. This unique molecular structure combines the long hydrocarbon chain of oleic acid with the reactivity of a cyclic boronate, making it a valuable intermediate for advanced organic synthesis and materials science. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and polymer industries for applications requiring precise boron incorporation or surface modification.

Application

• Pharmaceutical Intermediate: Used in the synthesis of boron-containing drug candidates, particularly for Boron Neutron Capture Therapy (BNCT) and protease inhibitors.
• Polymer Modification: Acts as a functional monomer or cross-linking agent to introduce hydrophobic oleyl chains and boronate ester groups into polymers, affecting properties like adhesion, self-healing, and responsiveness to diols.
• Surface Coating Agent: Employed to create hydrophobic or chemically reactive coatings on various substrates, including metals and glass.
• Agrochemical Synthesis: Serves as a building block for creating novel surfactants, adjuvants, or active ingredients with specific delivery or binding properties.
• Research & Development: A key reagent in organic chemistry for Suzuki-Miyaura and other cross-coupling reactions, leveraging the boronate ester functionality.
• Material Science: Used in the development of sensors and diagnostic materials that utilize the specific binding of boronate esters to cis-diols, such as sugars.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent hydrolysis and degradation. Keep away from strong oxidizers.
