API & Intermediates

API and pharmaceutical intermediates in this category include selected active ingredients and synthesis-stage compounds used in drug development and manufacturing routes. Examples include artemisinin, paracetamol, pregabalin, rivaroxaban, citicoline sodium, imidazole, amino compounds, and other functional intermediates identified by product name and CAS number.

Each inquiry should distinguish between an active ingredient and an intermediate and state the required grade, assay, impurity profile, analytical standard, batch size, and destination. Regulatory status and market authorization vary by product and country. Buyers should request current batch documentation, evaluate the manufacturing and quality requirements, and complete all necessary qualification before regulated or commercial use.
