For pharmaceutical manufacturers focused on producing Lornoxicam, a critical step involves sourcing high-quality intermediates. Methyl 5-chloro-3-(chlorosulfonyl)-2-thiophenecarboxylate (CAS: 126910-68-7) stands out as a pivotal building block in the synthesis pathway. This article aims to guide procurement managers and R&D scientists on how to effectively source this essential chemical, particularly from leading Chinese manufacturers.

Understanding the specifications is paramount. When you look to buy Methyl 5-chloro-3-(chlorosulfonyl)-2-thiophenecarboxylate, prioritize suppliers who can guarantee a high assay, typically above 95.0% as determined by HPLC. The appearance, noted as a yellow powder, is another key indicator of quality. Consistent physical properties ensure predictable reaction outcomes, minimizing batch-to-batch variations in your Lornoxicam production.

The journey from intermediate to Active Pharmaceutical Ingredient (API) requires a reliable supply chain. When considering a manufacturer in China for CAS 126910-68-7, it is crucial to assess their production capacity, quality control systems, and export experience. Companies like NINGBO INNO PHARMCHEM CO.,LTD. have established themselves as reputable suppliers, offering not only bulk quantities but also custom synthesis services tailored to specific project requirements. This flexibility is invaluable for R&D teams exploring novel routes or requiring specialized formulations.

When inquiring about the price of Methyl 5-chloro-3-(chlorosulfonyl)-2-thiophenecarboxylate, be prepared to discuss your required volume, purity standards, and delivery timelines. Bulk purchase agreements often lead to more favorable pricing. Furthermore, don't hesitate to request Certificates of Analysis (CoA) and Material Safety Data Sheets (MSDS) to thoroughly vet the product and ensure compliance with safety and regulatory standards. A proactive approach to sourcing will secure a consistent and cost-effective supply of this vital pharmaceutical intermediate.

In conclusion, sourcing Methyl 5-chloro-3-(chlorosulfonyl)-2-thiophenecarboxylate from China involves a strategic approach. By focusing on product specifications, supplier reputation, and clear communication regarding your needs, you can ensure a stable supply chain for your Lornoxicam manufacturing. We encourage you to reach out to experienced manufacturers for quotes and further information.
