For procurement managers and R&D scientists in the pharmaceutical sector, identifying reliable sources for critical intermediates like 4,6-Dichloro-1H-pyrrolo[2,3-b]pyridine (CAS 5912-18-5) is paramount. This heterocyclic compound, often referred to as 4,6-dichloro-7-azaindole, is a versatile building block in the synthesis of numerous APIs, particularly those targeting inflammatory conditions and certain types of cancer. Understanding the sourcing landscape and key considerations when you buy this intermediate is crucial for seamless R&D and production planning.

The chemical structure of 4,6-Dichloro-1H-pyrrolo[2,3-b]pyridine features a fused pyrrolo[2,3-b]pyridine ring system with chlorine substituents at the 4 and 6 positions. This specific arrangement confers unique reactivity, making it an ideal starting material for various synthetic transformations. Pharmaceutical intermediate manufacturers in China offer this compound, often with high purity levels (e.g., 98% or 99% min), which is essential for ensuring the quality and efficacy of the final drug product.

When evaluating a potential supplier, procurement managers should look for manufacturers with a proven track record in producing fine chemicals and pharmaceutical intermediates. Key factors to consider include product purity, consistency in quality, competitive pricing, and reliable global delivery. Companies specializing in custom synthesis and offering free samples are often good indicators of a supplier's commitment to quality and customer satisfaction. It's also beneficial to find a supplier that can provide comprehensive technical documentation, such as Certificates of Analysis (CoA) and Safety Data Sheets (SDS), to support your internal quality control processes.

The synthesis of 4,6-Dichloro-1H-pyrrolo[2,3-b]pyridine typically involves multi-step chemical processes. Manufacturers leverage advanced synthetic methodologies to achieve the required purity and yield. For instance, N-oxidation followed by halogenation using reagents like phosphorus oxychloride is a common route. The industrial-scale production demands optimized reaction conditions, efficient purification techniques (often employing chromatography), and stringent quality control measures at every stage. As a buyer, understanding these manufacturing aspects can help you better assess the capabilities of a potential chemical manufacturer.

For those looking to purchase 4,6-Dichloro-1H-pyrrolo[2,3-b]pyridine, engaging directly with established manufacturers or their authorized distributors is the most effective approach. This ensures you are obtaining genuine products at competitive prices, often with options for bulk purchasing and tailored delivery schedules. The goal for any procurement specialist is to secure a stable supply chain for critical raw materials. Therefore, building a strong relationship with a reliable chemical supplier in China can significantly benefit your company's ongoing research and production needs.
