For professionals in the chemical industry, sourcing high-quality intermediates is paramount to successful research and production. Among these, 3-Bromophthalide, identified by its CAS number 6940-49-4, stands out as a versatile building block. This article aims to guide procurement managers and R&D scientists through the process of identifying and acquiring this critical compound.

Understanding the Specifications: 3-Bromophthalide, with the molecular formula C8H5BrO2, is typically a white or light yellow crystalline solid. Its physical properties, such as a melting point of 86°C and a boiling point of 138°C at 3mmHg, are crucial for handling and reaction planning. Manufacturers often guarantee a purity of 99.5%min, ensuring its suitability for sensitive synthetic routes. When you buy 3-Bromophthalide, always verify these specifications to match your project's requirements.

Key Applications in Synthesis: The utility of 3-Bromophthalide (CAS 6940-49-4) spans various sectors. It is frequently employed as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and other fine chemicals. Its reactive bromine atom and phthalide core make it an excellent starting material for introducing specific functionalities into target molecules. For instance, R&D scientists often seek this compound to develop novel compounds with unique biological activities or material properties.

Navigating the Purchase Process: When looking to purchase 3-Bromophthalide, especially in bulk quantities, identifying a reliable manufacturer and supplier is key. Many buyers turn to China-based chemical manufacturers for competitive pricing and consistent supply. The inquiry process typically involves requesting a price quote for specific quantities, often starting from minimum order requirements like 500kg. Communicating your needs clearly, including desired purity levels and packaging (e.g., 25kg bags or drums), will streamline the procurement process.

Choosing the Right Supplier: A reputable supplier will not only offer competitive pricing but also provide essential documentation such as Certificates of Analysis (CoA) and Safety Data Sheets (SDS). When you buy 3-Bromophthalide from an established manufacturer, you gain confidence in the product's quality and the stability of its supply chain. These partnerships are vital for long-term project success. For those needing to buy this chemical intermediate, exploring options from trusted China suppliers ensures efficient sourcing for your chemical needs.
