The pharmaceutical landscape is constantly evolving, with a significant focus on developing advanced treatments for complex conditions like central nervous system (CNS) disorders. Brexpiprazole, a prominent medication in this area, relies on specific, high-quality intermediates for its synthesis. This article explores the critical role of 7-(4-Chlorobutoxy)-2(1H)-quinolinone (CAS 913613-82-8) in the manufacturing process of Brexpiprazole and discusses the importance of sourcing this compound from reputable chemical suppliers.

Brexpiprazole: A Breakthrough in CNS Treatment

Brexpiprazole is an atypical antipsychotic medication approved for the treatment of schizophrenia and as an adjunctive therapy for major depressive disorder. Its mechanism of action involves modulating dopamine and serotonin neurotransmitter systems in the brain. The efficacy and safety of such complex drugs are directly linked to the quality of the raw materials and intermediates used in their production. Therefore, the pharmaceutical industry places immense emphasis on sourcing intermediates with impeccable purity and well-defined chemical properties.

The Crucial Role of 7-(4-Chlorobutoxy)-2(1H)-quinolinone in Synthesis

7-(4-Chlorobutoxy)-2(1H)-quinolinone (Molecular Formula: C13H14ClNO2) serves as a key precursor in the multi-step synthesis of Brexpiprazole. The specific functional groups within this molecule are strategically utilized in subsequent chemical reactions to build the final API structure. Manufacturers often produce this intermediate through precise alkylation processes, ensuring a high degree of purity, typically 98% or higher, to meet stringent pharmaceutical standards. This compound's structure, a quinolinone derivative with a chlorobutoxy side chain, is perfectly suited for the synthetic routes that lead to Brexpiprazole. Understanding the CAS number 913613-82-8 is crucial for researchers and procurement specialists to correctly identify and source this specific chemical.

Why Partner with Reliable Suppliers?

The synthesis of pharmaceutical APIs is a highly regulated and complex process. Sourcing intermediates like 7-(4-Chlorobutoxy)-2(1H)-quinolinone requires a discerning approach to supplier selection. For companies looking to purchase this compound, partnering with experienced manufacturers, particularly those in China, offers significant advantages. These suppliers, such as NINGBO INNO PHARMCHEM CO.,LTD., are equipped with the technical expertise and manufacturing capabilities to produce high-purity intermediates consistently. When evaluating potential suppliers, it is important to:

  • Verify their quality management systems and certifications.
  • Request comprehensive Certificates of Analysis (CoAs) for each batch.
  • Inquire about their production capacity and lead times for bulk orders.
  • Ensure they can provide necessary safety data sheets (MSDS) and technical support.

By establishing a robust supply chain, pharmaceutical companies can guarantee the timely availability of essential raw materials, thereby preventing delays in drug production and development timelines. The competitive pricing offered by many Chinese chemical manufacturers further enhances the economic viability of these partnerships.

Conclusion: Driving Pharmaceutical Innovation Through Quality Intermediates

The journey from laboratory research to a marketable drug is long and intricate. Key intermediates like 7-(4-Chlorobutoxy)-2(1H)-quinolinone are foundational to this process. By understanding its chemical properties, applications, and the importance of quality sourcing, pharmaceutical companies can ensure the efficient and reliable production of vital CNS therapies like Brexpiprazole. Partnering with trusted manufacturers who prioritize purity and consistency is a strategic imperative for success in the competitive pharmaceutical market.
