Description

2-Propenoic Acid,2-Methyl-,4-Boronophenyl Ester is a specialized organoboron monomer that incorporates both a polymerizable methacrylate group and a boronic acid ester functionality. This unique structure makes it a critical building block for advanced materials, particularly in the development of stimuli-responsive polymers and functional coatings. It is primarily sought by R&D chemists and material scientists in the polymer, adhesive, and specialty chemical industries for creating novel materials with tailored properties.

Application

• Stimuli-Responsive (Smart) Polymers: Serves as a key monomer for synthesizing hydrogels and polymers that respond to changes in pH, glucose, or other analytes, useful in biomedical and sensor applications.
• Functional Coatings and Adhesives: Used to introduce boronic ester groups into acrylic polymer backbones, enabling cross-linking or adhesion to diol-containing surfaces.
• Pharmaceutical Intermediate: Acts as a precursor in the synthesis of more complex boron-containing compounds for drug discovery and development.
• Material Science Research: Employed in academic and industrial R&D for exploring new polymer architectures, self-healing materials, and organic electronics.
• Chromatography and Separation Media: Can be grafted onto silica or polymer supports to create affinity columns for the separation of sugars, glycoproteins, or catechols.

Quality Control

Every batch of 2-Propenoic Acid,2-Methyl-,4-Boronophenyl Ester is produced and tested under strict quality management protocols. We ensure high purity and consistency through advanced analytical techniques including NMR, HPLC, and GC. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each 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 room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
