For chemical procurement managers, sourcing Active Pharmaceutical Ingredients (APIs) like Finasteride (CAS 98319-26-7) involves a detailed understanding of product specifications and supplier capabilities. Ensuring the procured material meets stringent quality standards is fundamental to the success of pharmaceutical product development and manufacturing. This article highlights the key specifications and considerations when purchasing Finasteride powder from Chinese manufacturers.

The primary specification for Finasteride powder revolves around its purity and physical form. Pharmaceutical-grade Finasteride is typically an almost white crystalline powder. Crucially, its assay, determined by methods like HPLC, should be consistently above 99%. This high purity level is critical for ensuring the therapeutic efficacy and safety of the final drug product used for conditions such as BPH and hair loss. Any impurities, even in small amounts, can affect the performance and regulatory compliance of the finished pharmaceutical. Therefore, always request a Certificate of Analysis (COA) detailing the assay and impurity profile.

Beyond purity, particle size distribution can also be an important factor, especially for formulation processes like tablet manufacturing or topical applications. Specifications often mention requirements like 100% passing through a 20um sieve and 90% passing through a 10um sieve. Understanding these granular details allows procurement managers to match the API to their specific manufacturing processes, ensuring smooth integration and optimal product performance. When you decide to buy Finasteride powder, clarifying these particle size requirements with the supplier is advisable.

Another vital aspect is the supplier's compliance with international quality standards. Look for manufacturers who hold certifications such as GMP, ISO 9001, USP, and BP. These credentials demonstrate a commitment to quality management systems and product integrity. A well-established supplier will also have a robust quality control system in place, with capabilities for advanced testing like UV and TLC, ensuring batch-to-batch consistency.

When negotiating bulk orders, factors like production capacity, lead times, and packaging options become equally important. Manufacturers in China often have large production capacities (e.g., 3000kg/month) and can offer competitive pricing. Discussing packaging, such as 25kg cartons or custom foil bags, and delivery terms early in the process will help streamline the procurement process. For your next sourcing requirement, consider partnering with a reputable Chinese manufacturer for your Finasteride powder needs; requesting samples and detailed specifications is a key first step to ensure a successful purchase.
