For procurement managers and R&D scientists in the chemical and pharmaceutical industries, sourcing high-quality raw materials is a non-negotiable aspect of successful operations. 3-Aminophenylboronic Acid Monohydrate (CAS 206658-89-1) is one such critical intermediate, widely recognized for its utility in organic synthesis, particularly for preparing pharmaceutical intermediates and various aryl compounds. When it comes time to buy this essential chemical, understanding the landscape of manufacturers and suppliers is crucial to ensure you receive a product that meets your stringent requirements.

The primary application driving the demand for 3-Aminophenylboronic Acid Monohydrate is its role as a building block in complex chemical synthesis. Its structure, featuring both an amino group and a boronic acid functionality, makes it a versatile reagent for a wide array of reactions. Most notably, it is a key component in palladium-catalyzed cross-coupling reactions, such as the Suzuki-Miyaura coupling, which is fundamental for forming new carbon-carbon bonds. This capability is indispensable in the synthesis of many active pharmaceutical ingredients (APIs) and advanced organic molecules. Therefore, purity and consistency are paramount.

When evaluating potential suppliers, several key factors should be considered. Firstly, the purity of the product is critical. Manufacturers often specify purity levels, such as 97% Min. for 3-Aminophenylboronic Acid Monohydrate. While this is a standard for many applications, higher purities might be necessary for highly sensitive pharmaceutical syntheses. It's also important to understand the physical form of the product – whether it is a powder or crystals, and its color (e.g., white to light yellow). These attributes can sometimes indicate processing differences or minor impurities.

Secondly, the reliability of the supplier or manufacturer is a significant consideration. A supplier based in China, for instance, can often offer competitive pricing due to manufacturing advantages. However, it is essential to vet these suppliers thoroughly. Look for companies with a proven track record, clear quality control processes, and a commitment to customer service. Requesting a free sample can be an excellent way to assess the product's quality firsthand before committing to a larger purchase. Understanding their production capacity and lead times is also vital for ensuring supply chain stability.

The CAS number, 206658-89-1, serves as a universal identifier for this compound, ensuring you are procuring the correct chemical. When you contact a manufacturer for a quote, be prepared to specify the quantity you need. Suppliers typically offer various pack sizes, from grams for R&D purposes to kilograms or tons for industrial production. The price per unit often decreases significantly with larger order volumes.

Furthermore, consider the overall service offered. A good supplier will provide comprehensive technical data sheets, safety information (MSDS), and responsive customer support. For specialized needs, inquiring about custom synthesis services for related boronic acid derivatives can also be beneficial. By carefully evaluating these aspects, R&D scientists and procurement specialists can confidently purchase 3-Aminophenylboronic Acid Monohydrate, ensuring their projects benefit from a reliable and high-quality chemical intermediate.
