The pharmaceutical industry relies heavily on a complex network of chemical intermediates to bring life-saving and life-enhancing drugs to market. Among these vital components is 4-Chloropyrrolo[2,3-d]pyrimidine (CAS: 3680-69-1), a crucial intermediate in the synthesis of Tofacitinib. Understanding its role and how to source it effectively is key for drug manufacturers and researchers.

Tofacitinib is a targeted therapy, specifically a Janus kinase (JAK) inhibitor, widely used to treat conditions such as rheumatoid arthritis, psoriatic arthritis, and ulcerative colitis. The synthesis of Tofacitinib is a multi-step process, and 4-Chloropyrrolo[2,3-d]pyrimidine serves as a foundational building block, providing the core pyrrolo[2,3-d]pyrimidine ring structure.

For pharmaceutical companies looking to buy 4-Chloropyrrolo[2,3-d]pyrimidine, ensuring high purity (typically ≥98.0% assay) is paramount. Impurities in this intermediate can lead to complications in subsequent reaction steps, potentially affecting the final API’s quality, yield, and regulatory compliance. This makes the choice of manufacturer and supplier critically important.
