In the complex landscape of pharmaceutical manufacturing, the precise synthesis of Active Pharmaceutical Ingredients (APIs) relies heavily on the quality and availability of crucial intermediates. Among these, 4-Amino-2,5-dichlorobenzenesulfonic acid, identified by its CAS number 88-50-6, stands out as a significant building block. As a dedicated pharmaceutical intermediate supplier, we understand the stringent demands of this industry and are committed to providing high-purity compounds that meet exacting standards.

What is CAS 88-50-6?
4-Amino-2,5-dichlorobenzenesulfonic acid is an organic chemical compound belonging to the class of sulfonated aromatic amines. Its unique chemical structure, featuring amino and sulfonic acid groups along with chlorine substituents on a benzene ring, makes it a versatile precursor in organic synthesis. Its common synonyms include 2,5-dichlorosulfanilic acid, underscoring its chemical lineage.

Key Applications in Pharmaceuticals
The primary application of CAS 88-50-6 lies in its role as an intermediate for synthesizing more complex pharmaceutical molecules. Its structure allows for various chemical modifications, enabling R&D scientists and product formulators to build sophisticated drug candidates. Specifically, it is utilized in pathways that lead to the development of specific therapeutic agents where its chlorine and sulfonic acid functionalities are integral to the final molecule's activity or pharmacokinetic properties. For procurement managers looking to buy pharmaceutical intermediates, ensuring a consistent supply of high-purity CAS 88-50-6 from reliable China manufacturers is essential for R&D and scaled production.

The Importance of Purity and Quality for Manufacturers
The efficacy, safety, and regulatory approval of pharmaceutical products are directly tied to the quality of their constituent intermediates. A purity level of ≥98.00%, as offered by many reputable Chinese manufacturers for this compound, is critical. Trace impurities can lead to unwanted side reactions, reduced yields, or even introduce toxicological concerns in the final API. Therefore, rigorous quality control and detailed analytical data, such as Certificates of Analysis (CoA), are non-negotiable when purchasing CAS 88-50-6 for pharmaceutical applications.

Sourcing Strategies for Pharmaceutical Intermediates
When sourcing pharmaceutical intermediates like 4-Amino-2,5-dichlorobenzenesulfonic acid, establishing a partnership with a dependable manufacturer is key. Many global pharmaceutical companies rely on specialized chemical suppliers in China due to their advanced manufacturing capabilities and competitive pricing. These suppliers often provide excellent logistical support, ensuring timely delivery in suitable packaging (e.g., 25kg bags) and accommodating bulk purchase inquiries. Companies looking for a consistent source of CAS 88-50-6 can benefit from direct inquiries to manufacturers for price quotations and sample requests.
