NINGBO INNO PHARMCHEM CO.,LTD. is pleased to offer a reliable supply of high purity 4-Vinylbenzyl Chloride, a critical chemical intermediate known by the CAS number 1592-20-7. This compound, also frequently referred to as 4-VBC, is a cornerstone building block in the synthesis of various high-performance polymers and specialized organic chemicals. Its unique molecular structure, featuring both a reactive vinyl group and a functional benzyl chloride moiety, endows it with exceptional versatility, making it indispensable in numerous industrial and research applications.

As a clear yellow liquid, 4-Vinylbenzyl Chloride possesses distinct physical characteristics that are important for its handling, storage, and processing. It has a reported boiling point of approximately 229 °C and a density around 1.083 g/mL at 25 °C. The vapor density relative to air is about 5.3, and it exhibits a vapor pressure of 1 mm Hg at 56.1 °C. Its refractive index is approximately 1.572 at 20 °C. These physical parameters are crucial for engineering processes involving distillation, mixing, and reaction design.

Handling and storage require careful consideration due to its reactivity and flash point, which is around 221 °F. Recommended storage conditions typically involve maintaining temperatures between 2-8°C to preserve its stability and prevent unwanted polymerization or degradation. NINGBO INNO PHARMCHEM CO.,LTD. adheres to stringent quality control measures to ensure the stability and purity of the 4-Vinylbenzyl Chloride supplied, ensuring it meets the demands of sensitive downstream applications.

The chemical reactivity of 4-Vinylbenzyl Chloride stems from its two functional groups. The vinyl group readily participates in addition polymerization, allowing it to form homopolymers like poly(4-vinylbenzyl chloride) (PVBC) or copolymerize with other monomers to create polymers with tailored properties. The benzyl chloride group, on the other hand, is highly reactive towards nucleophilic substitution reactions. This allows for the facile introduction of various functional groups onto the polymer backbone or in other chemical syntheses, opening up a wide range of possibilities for creating functional materials.

One of the primary applications of 4-Vinylbenzyl Chloride is in the production of ion exchange resins. By reacting the benzyl chloride group with amines or other nucleophiles, ionic functionalities can be grafted onto a polymer matrix, typically a cross-linked styrene-divinylbenzene copolymer incorporating 4-VBC units. These resins are vital for water purification, chromatography, catalysis, and metal recovery, highlighting the crucial role of 4-VBC in environmental and industrial processes.

Furthermore, 4-Vinylbenzyl Chloride is a key component in the formulation of polymers used in photoresist materials. In the microelectronics industry, photoresists are essential for pattern transfer during the fabrication of integrated circuits. Polymers derived from 4-VBC can be designed to change their solubility upon exposure to light or electron beams, enabling the precise definition of intricate patterns on semiconductor wafers. Its inclusion provides the necessary reactivity and chemical resistance required for these demanding applications.

Beyond these major uses, 4-VBC finds application in the creation of cross-linked fibers and specialized coatings. Its bifunctional nature makes it an excellent candidate for developing polymers with enhanced mechanical strength, thermal stability, and chemical resistance through cross-linking reactions. It also serves as a valuable starting material for synthesizing coupling agents, substances used to promote adhesion between dissimilar materials, such as polymers and inorganic fillers.

The versatile reactivity of 4-Vinylbenzyl Chloride also extends to its use in developing conductive polymers or matrices for conductive composites. While PVBC itself is insulating, the reactive benzyl chloride group can be functionalized to attach conductive moieties or facilitate the incorporation of conductive fillers like carbon nanotubes or conductive polymers through grafting techniques. This contributes to the development of materials for antistatic coatings, sensors, and electronic components.

Research and development continue to explore new applications for 4-Vinylbenzyl Chloride in areas such as chromatography stationary phases, solid-phase synthesis supports, and materials for diagnostics and drug delivery systems (as a component of the delivery matrix, not the drug itself). Its ability to create polymers with easily modifiable backbones makes it a valuable tool for chemists and material scientists pushing the boundaries of polymer science.

Ensuring high purity is paramount for consistent performance in all these advanced applications. Impurities in 4-VBC can interfere with polymerization kinetics, reduce reactivity of the benzyl chloride group, or negatively impact the final properties of the derived materials. NINGBO INNO PHARMCHEM CO.,LTD. understands these critical requirements and maintains rigorous quality control protocols to deliver 4-Vinylbenzyl Chloride that meets the high standards expected by the industry.
