Description

3-(Boronooxy)-2-Hydroxypropyl Stearate is a specialized organoboron compound that combines the properties of a fatty acid ester with a boronic acid ester functionality. This unique structure makes it a valuable intermediate for synthesizing advanced materials and functional additives where controlled hydrophobicity and boron-mediated reactivity are required. It is primarily sought by R&D chemists and process engineers in the pharmaceutical, polymer, and specialty chemical industries for applications ranging from novel drug delivery systems to polymer cross-linking agents.

Application

• Pharmaceutical Intermediate: Used in the synthesis of boron-containing active pharmaceutical ingredients (APIs) and prodrugs, particularly for boron neutron capture therapy (BNCT) and other targeted therapies.
• Polymer Modification & Cross-linking Agent: Serves as a reactive monomer or cross-linker to introduce boron functionalities into polymers, enhancing properties like thermal stability or creating stimuli-responsive materials.
• Surface Modification & Coatings: Acts as an adhesion promoter or surface-modifying agent for coatings, leveraging the stearyl chain for hydrophobicity and the boronate group for substrate binding.
• Specialty Additive Synthesis: A key building block for creating lubricant additives, corrosion inhibitors, or stabilizers where the combination of long alkyl chain and boron chemistry is beneficial.
• Research & Development: Employed in academic and industrial R&D for exploring new organoboron chemistry, catalytic applications, and material science.

Quality Control

Our production of 3-(Boronooxy)-2-Hydroxypropyl Stearate adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. Each lot is characterized using advanced analytical techniques including NMR, HPLC, and FTIR to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical specifications is provided with every shipment 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 a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to minimize exposure to atmospheric moisture, which can lead to hydrolysis of the boronic ester group.
