For professionals in the pharmaceutical and chemical industries, sourcing reliable and high-quality intermediates is paramount. 5-Chlorothiophene-2-carboxylic acid (CAS 24065-33-6) stands out as a critical component, particularly for the synthesis of Rivaroxaban. When looking to buy 5-Chlorothiophene-2-carboxylic acid, understanding key considerations will ensure you partner with a reputable manufacturer in China.

Purity is Paramount: The efficacy and safety of the final product heavily depend on the purity of the intermediates used. Always inquire about the purity levels, typically stated as ≥98% or ≥99% via HPLC. Reputable suppliers will readily provide Certificates of Analysis (COA) detailing these specifications. Ensuring high purity minimizes downstream processing issues and guarantees the integrity of your research or production batches.

Understanding Synthesis Routes: While the source of the intermediate is important, understanding its synthesis can also provide valuable insights. Various methods exist, utilizing starting materials like 2-chlorothiophene or 2-chloro-5-bromothiophene. A knowledgeable supplier can often discuss these aspects, demonstrating their technical expertise.

Supplier Reliability and Stability: Beyond product quality, consider the supplier's track record. A stable supply chain, consistent production capacity, and adherence to quality management systems (like ISO certification) are crucial indicators of a reliable partner. For international procurement, understanding lead times, payment terms (L/C, T/T, etc.), and incoterms (FOB, CFR, CIF) is also vital for smooth transactions.

Competitive Pricing and Bulk Orders: When scaling up production, securing competitive pricing is essential. Manufacturers often offer tiered pricing based on order volume. Reaching out for a quote for bulk quantities of 5-Chlorothiophene-2-carboxylic acid from established Chinese suppliers can lead to significant cost savings.

Application-Specific Needs: While its primary use is as a Rivaroxaban intermediate, 5-Chlorothiophene-2-carboxylic acid also finds application in broader organic synthesis and potentially in material science. Confirming that the supplied grade meets your specific application requirements is always recommended.
