For professionals in the pharmaceutical manufacturing sector, a thorough understanding of chemical intermediates' specifications is critical for successful product development and production. Montelukast, identified by CAS number 158966-92-8, is a significant pharmaceutical intermediate primarily used in the treatment of asthma and allergic rhinitis. Buyers must be well-informed about its key properties to ensure they procure a product that meets stringent quality requirements.

The essential specifications for Montelukast typically include its appearance and purity. It is commonly supplied as a white to off-white powder, a physical characteristic that aids in its formulation. The purity level is a paramount concern, with 98% being a standard benchmark for pharmaceutical applications. This high purity ensures that the final drug product is safe and effective, minimizing the presence of impurities that could affect therapeutic outcomes or patient safety.

When considering the procurement of Montelukast, prospective buyers often look towards China for its robust chemical manufacturing industry. Partnering with a reliable manufacturer or supplier in this region can offer distinct advantages, including competitive pricing and a broad range of payment and shipping options. Essential commercial terms to clarify include payment methods (such as T/T, L/C) and delivery Incoterms (like FOB, CFR, EXW), which govern the responsibilities and costs associated with transportation.

Furthermore, establishing the reliability of a supplier is key. This involves reviewing their quality certifications, manufacturing capabilities, and track record in the pharmaceutical supply chain. Requesting samples for in-house testing and obtaining detailed product documentation, such as Certificates of Analysis (CoA), are standard practices for verifying quality and suitability for intended use.

In summary, for any pharmaceutical company looking to buy Montelukast, a detailed focus on its specifications—particularly purity and appearance—coupled with a strategic approach to sourcing from reputable Chinese manufacturers and suppliers, is essential for ensuring product quality and operational efficiency.
