Procurement professionals in the pharmaceutical and fine chemical industries often face the challenge of sourcing specialized intermediates. Pyrazole-4-boronic acid pinacol ester (CAS 269410-08-4) is one such critical compound, essential for the synthesis of key pharmaceutical ingredients. This guide aims to assist buyers in understanding the importance of quality, reliability, and the process of acquiring this intermediate from reputable sources.

Understanding the Product: Pyrazole-4-Boronic Acid Pinacol Ester

Pyrazole-4-boronic acid pinacol ester is a chemical compound typically supplied as a white to light yellow solid. Its purity is a paramount consideration for pharmaceutical applications, with levels often specified at 98% or higher. The molecule's structure, featuring a pyrazole ring and a boronic acid pinacol ester group, makes it a versatile intermediate in complex organic synthesis. It is frequently employed in Suzuki-Miyaura coupling reactions, a fundamental tool for C-C bond formation in medicinal chemistry.

Key Applications Driving Demand

The primary application that drives the demand for Pyrazole-4-boronic acid pinacol ester is its use in the synthesis of Ruxolitinib Phosphate. Ruxolitinib is a Janus kinase (JAK) inhibitor used in treating myelofibrosis and polycythemia vera, among other conditions. The precise incorporation of the pyrazole moiety via this intermediate is crucial for the drug's efficacy. Furthermore, its utility extends to the development of other kinase inhibitors and various biologically active compounds, making it a valuable asset in drug discovery pipelines.

Finding a Reliable Manufacturer and Supplier

When you need to buy Pyrazole-4-boronic acid pinacol ester, it is essential to partner with a trustworthy manufacturer. Look for suppliers who demonstrate a strong commitment to quality control, often evidenced by certifications like ISO 9001. Manufacturers in China are known for their robust chemical synthesis capabilities and competitive pricing. Ensuring a stable supply chain is equally important; a reliable supplier will have robust production capacity and efficient logistics to meet your volume requirements consistently.

Key Considerations for Procurement

• Purity: Always verify that the product meets the required purity specifications (e.g., >=98%) for your specific application.
• CAS Number: Confirm the CAS number is indeed 269410-08-4 to ensure you are procuring the correct chemical entity.
• Supplier Reputation: Research potential suppliers for their track record, customer reviews, and adherence to quality standards.
• Pricing and Volume: Obtain quotes for both research-scale and bulk quantities to understand cost-effectiveness and scalability.
• Lead Times: Inquire about production and shipping lead times to integrate the procurement process into your project timelines.
