For procurement managers and R&D scientists in the pharmaceutical sector, securing a consistent and high-quality supply of critical intermediates is paramount. One such compound is 3-Nitrophthalic Anhydride (CAS: 641-70-3), a vital precursor in the synthesis of Pomalidomide. If you are looking to buy this essential chemical, understanding its role and identifying reputable manufacturers and suppliers is crucial for successful drug production.

Pomalidomide is a potent immunomodulatory drug widely used in the treatment of multiple myeloma and other hematological malignancies. Its complex synthesis relies on specific, high-purity starting materials, with 3-Nitrophthalic Anhydride being a cornerstone intermediate. The quality of this anhydride directly impacts the efficiency of the synthesis process and the purity of the final Active Pharmaceutical Ingredient (API).

When sourcing 3-Nitrophthalic Anhydride, B2B buyers typically seek specific attributes. Purity is a primary concern, with many requiring assays of 98% or higher, often verified by HPLC. Chemical stability, reliable packaging, and adherence to safety protocols are also critical. For procurement managers, understanding the sourcing landscape, particularly identifying trusted 3-Nitrophthalic Anhydride manufacturers in China, is key to competitive pricing and assured supply.

The process of synthesizing Pomalidomide involves several steps, with 3-Nitrophthalic Anhydride typically reacting with 3-Aminopiperidine-2,6-Dione. This reaction, followed by catalytic hydrogenation of the nitro group, leads to the formation of the core structure of Pomalidomide. Therefore, the quality and reactivity of the 3-Nitrophthalic Anhydride as a chemical intermediate significantly influence the overall yield and cost-effectiveness of the Pomalidomide production.

For those looking to purchase 3-Nitrophthalic Anhydride, exploring suppliers that offer comprehensive documentation, such as Certificates of Analysis (CoA) and Material Safety Data Sheets (MSDS), is advisable. Companies specializing in fine chemical intermediates often provide these essential documents, ensuring transparency and regulatory compliance. Furthermore, inquire about bulk quantities and customized packaging options that align with your manufacturing facility's needs.
