For procurement managers and R&D scientists in the pharmaceutical industry, sourcing high-quality Active Pharmaceutical Ingredient (API) intermediates is paramount to successful drug development and manufacturing. One such critical intermediate is methyl 6-chloro-4-hydroxy-1,1-dioxo-2H-thieno[2,3-e]thiazine-3-carboxylate, commonly identified by its CAS number 70374-51-5. This compound plays a pivotal role in the synthesis of Lornoxicam, a widely used non-steroidal anti-inflammatory drug (NSAID).

When looking to buy CAS 70374-51-5, several factors come into play. The primary concern for any B2B buyer is the purity and consistency of the chemical. A high assay, typically above 98.0% as confirmed by HPLC, is crucial for ensuring efficient reaction yields and minimizing unwanted byproducts in the Lornoxicam synthesis. Manufacturers and suppliers who provide detailed Certificates of Analysis (CoA) and adhere to strict quality control measures are essential partners.

Price is, of course, another significant consideration. Pharmaceutical buyers often seek competitive pricing without compromising on quality. Understanding the market for intermediates like 70374-51-5 requires diligence in comparing offers from various manufacturers and suppliers, particularly those based in key chemical manufacturing hubs like China. Requesting a detailed quote from a reputable supplier will provide clarity on the cost-effectiveness of your sourcing strategy.

Furthermore, supply chain reliability is non-negotiable. A consistent supply of pharmaceutical intermediates ensures uninterrupted production schedules. Buyers should look for suppliers who can demonstrate robust manufacturing capabilities, adequate inventory management, and efficient logistics. Working with a manufacturer that offers flexible packaging options, such as 25 kg drums, can also simplify handling and storage.

In summary, when you need to purchase pharmaceutical intermediates such as methyl 6-chloro-4-hydroxy-1,1-dioxo-2H-thieno[2,3-e]thiazine-3-carboxylate (CAS 70374-51-5) for Lornoxicam synthesis, prioritize purity, competitive price, and supply chain stability.
