4-Vinylbenzoic acid

Description of 4-Vinylbenzoic acid

4-Vinylbenzoic acid (CAS: 1075-49-6) is a versatile vinyl monomer. In polymer chemistry, it serves as a key building block for acrylic resins, coatings, and adhesives, enabling pH-sensitive hydrogels and functional surfaces in biomedical and optical applications.

Application of 4-Vinylbenzoic acid

4-Vinylbenzoic acid (4-VBA) is a reactive vinyl monomer widely used in polymer chemistry as a building block for synthesizing specialty polymers, including molecularly imprinted polymers (MIPs) that enhance selectivity for sensor and separation applications. It improves thermal stability, mechanical strength, and adhesion in high-performance coatings, adhesives, and sealants for automotive, construction, and corrosion-resistant industrial uses. As a pharmaceutical intermediate, it supports the development of therapeutic agents and drug delivery systems, while its derivatives enable biosensing technologies.

Storage of 4-Vinylbenzoic acid

4-Vinylbenzoic acid is light- and heat-sensitive, requiring refrigerated storage at 0-10°C in a cool, dry environment to prevent polymerization and degradation. Use amber or opaque containers to protect from light exposure, and seal airtight to minimize moisture. Under inert atmosphere if handling large quantities. Avoid freezing or temperature fluctuations.
