In the intricate process of drug discovery and development, the selection of high-quality intermediates is a cornerstone for success. One such compound, identified by CAS number 183321-69-9, plays a pivotal role in the synthesis of various pharmaceutical agents. This article highlights the importance of this specific chemical, commonly supplied as a white powder with a purity of ≥99%, and explores the advantages of sourcing it from specialized manufacturers in China. For R&D scientists and procurement specialists, understanding its applications and procurement channels is crucial.

Understanding CAS 183321-69-9: A Versatile Intermediate

The chemical structure of 2H-Isoindole-2-ethanesulfonamide, N-[4-[(3-ethynylphenyl)amino]-6-quinazolinyl]-1,3-dihydro-1,3-dioxo- (CAS 183321-69-9) lends itself to a variety of synthetic pathways, making it a valuable intermediate in the pharmaceutical industry. Its specific molecular architecture allows for further functionalization and incorporation into complex drug molecules. The requirement for high purity (≥99%) is essential, as any impurities could potentially interfere with downstream reactions or impact the final API's efficacy and safety profile. When researchers look to buy this compound, they are seeking a reliable source that guarantees this level of chemical integrity.

Applications in API Synthesis

The primary application of CAS 183321-69-9 lies in its function as a precursor or intermediate for Active Pharmaceutical Ingredients (APIs). It can be a critical component in the synthesis of targeted therapies, particularly in areas such as oncology, where complex molecular structures are often required. Drug developers often need to purchase this intermediate in significant quantities for their research and development pipelines, and subsequently for larger-scale manufacturing. The ability to source this material from a reputable supplier who can ensure consistent quality and large-scale production is vital for the timely progression of drug candidates through clinical trials and to market.

Leveraging Chinese Manufacturers for Cost-Effective Sourcing

China has established itself as a leading global hub for chemical synthesis and manufacturing. For pharmaceutical companies worldwide, sourcing intermediates like CAS 183321-69-9 from Chinese manufacturers offers distinct advantages, including competitive prices and access to advanced production capabilities. Companies such as NINGBO INNO PHARMCHEM CO.,LTD. specialize in producing these high-purity intermediates, leveraging their expertise and infrastructure to meet global demand. When looking to purchase these chemicals, selecting a manufacturer with a proven track record in quality control and export operations is key to a successful procurement strategy.

Procurement Strategies for R&D and Production

For R&D scientists, obtaining small, high-purity samples of CAS 183321-69-9 for initial screening and synthesis experiments is crucial. For production teams, securing a stable, long-term supply of this intermediate at consistent quality and competitive prices is paramount. This often involves establishing strong relationships with chosen suppliers and potentially entering into supply agreements. Understanding the lead times, packaging options, and shipping capabilities of the manufacturer will ensure that your production timelines are met without disruption. As you plan your next API synthesis project, consider the strategic advantages of partnering with a dedicated Chinese manufacturer.

The availability of high-purity pharmaceutical intermediates like CAS 183321-69-9 from specialized Chinese chemical suppliers empowers pharmaceutical innovation globally, driving the development of new and improved therapeutics.
