In the rigorous landscape of pharmaceutical manufacturing, the purity of Active Pharmaceutical Ingredient (API) intermediates is a non-negotiable aspect that directly impacts the safety, efficacy, and regulatory compliance of the final drug product. Ethyl N-[5-(4-methylphenyl)sulfonyl]-5H-pyrrolo[2,3-b]pyrazin-2-ylcarbamate (CAS 1869118-24-0), a key intermediate in the synthesis of Upadacitinib, serves as an excellent case study for understanding these critical purity standards.

The typical specification for this intermediate requires a purity of ≥98.0%, with individual impurities controlled to ≤2.0%. Water content is also monitored, usually kept at ≤1.0%. These precise analytical standards ensure that downstream synthesis steps proceed smoothly and that the final API meets stringent pharmaceutical quality requirements. As a leading supplier of this compound, we meticulously adhere to these quality control measures. Our commitment extends to providing detailed Certificates of Analysis with each batch, giving our clients confidence when they buy or purchase this essential chemical.
