For B2B procurement professionals and research scientists in the pharmaceutical and chemical industries, the selection of Aprotinin (CAS 9087-70-1) as a raw material or intermediate is a decision that hinges on several critical factors. This polypeptide's unique enzymatic inhibitory properties make it a sought-after compound, driving the need for a strategic sourcing approach.

The primary application of Aprotinin lies in its role as a pharmaceutical intermediate. It is instrumental in the formulation of drugs for treating acute pancreatitis, managing hemorrhages, and preventing postoperative complications. For any buyer, understanding these applications helps in defining the required quality specifications. The standard quality benchmarks, such as USP38 and EP7.0, are crucial indicators of purity and suitability for pharmaceutical use. When searching to buy Aprotinin, prioritizing suppliers who explicitly meet these standards is essential.

The global supply of Aprotinin is increasingly influenced by manufacturers from China. Companies looking for cost-effective procurement solutions often search for 'Aprotinin manufacturer China' or 'CAS 9087-70-1 supplier'. These manufacturers are known for their production capacity and competitive pricing, making them attractive partners for both small-scale research needs and large-volume industrial procurement. The typical appearance of Aprotinin as a white or yellowish powder, along with standard packaging like 1kg/bag, are common details provided by these suppliers.

When evaluating potential Aprotinin suppliers, B2B buyers should consider several aspects beyond just price. This includes the supplier's track record, their ability to provide Certificates of Analysis (CoA), and their responsiveness to inquiries. Terms like 'Aprotinin wholesale price' or 'bulk Aprotinin for sale' indicate potential cost savings, but these must be balanced against the supplier's reliability and adherence to quality control protocols.

Ultimately, securing a steady supply of Aprotinin involves diligent research and building strong relationships with manufacturers. By focusing on quality certifications, competitive pricing from reputable China-based suppliers, and clear communication regarding product specifications and delivery, B2B buyers can effectively meet their sourcing requirements for this vital pharmaceutical compound.
