For procurement managers in the chemical industry, sourcing critical intermediates like 4-Vinylphenylboronic Acid (CAS: 2156-04-9) demands a strategic approach. Understanding the product's specifications, typical applications, and identifying trustworthy manufacturers are paramount to ensuring consistent quality and a stable supply chain. This guide focuses on these key aspects, helping B2B buyers make informed decisions when looking to buy 4-Vinylphenylboronic Acid.

Understanding 4-Vinylphenylboronic Acid: Properties and Applications

4-Vinylphenylboronic Acid is a bifunctional molecule renowned for its utility in advanced chemical synthesis. Its typical appearance is a white to pale beige crystalline powder, with a high purity level, often exceeding 95% or even 99% as specified by manufacturers. Its molecular formula is C8H9BO2, with a molecular weight of approximately 147.97 g/mol. This compound is extensively used in:

• Suzuki Coupling Reactions: It serves as a key coupling partner in Palladium-catalyzed Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds to create complex organic molecules. This makes it invaluable in the synthesis of pharmaceuticals, agrochemicals, and advanced materials.
• Polymer Chemistry: The vinyl group allows for polymerization, leading to the creation of functionalized polymers with tailored electronic or optical properties. This is particularly relevant in the development of smart materials, sensors, and advanced coatings.
• Agrochemical Synthesis: As an important intermediate, it plays a role in the development of new pesticides and herbicides, contributing to more effective crop protection solutions.
• Materials Science: Its ability to form complexes with diols makes it useful in developing novel sensors and materials for diverse applications.

Key Considerations When Purchasing 4-Vinylphenylboronic Acid

When you are ready to purchase 4-Vinylphenylboronic Acid, several factors should guide your choice of supplier:

• Purity Levels: Ensure the stated purity meets your application's requirements. Higher purity often translates to better reaction yields and fewer side products. Always request Certificates of Analysis (COA) to verify product specifications.
• Manufacturer Reputation: Look for established manufacturers with a proven track record of quality and reliability. Companies in China, like NINGBO INNO PHARMCHEM CO.,LTD., often offer competitive pricing and high-quality intermediates due to their robust chemical manufacturing infrastructure.
• Supply Chain Stability: A reliable manufacturer will demonstrate a stable production capacity and efficient logistics to ensure timely delivery, which is critical for maintaining production schedules.
• Technical Support and Documentation: Access to comprehensive Safety Data Sheets (SDS) and technical support can streamline your procurement and handling processes.

Finding a Reputable Supplier for Your Needs

For businesses seeking to buy 4-Vinylphenylboronic Acid in bulk or for research purposes, it is advisable to partner with suppliers who prioritize quality control and customer service. Examining supplier websites for detailed product information, including CAS number (2156-04-9) and availability, is a good starting point. Requesting a quote or a free sample can also provide valuable insights into product quality and supplier responsiveness. When you need a dependable source for this essential chemical, consider leading manufacturers in China that can meet stringent quality and volume demands.
