Considering a partnership? Discover the benefits of Outsourcing Custom Synthesis
Every custom synthesis project progresses through a structured, quality-driven workflow to ensure precision, reproducibility, and scalability. It begins with project evaluation, where client requirements and scientific feasibility are reviewed, followed by synthetic route design to optimize reaction pathways. The compound is then produced through bench-scale laboratory synthesis under controlled conditions, after which purification and full characterization are performed using techniques such as NMR, HPLC, and GC-MS. Once the process is proven, it moves into scale-up for pilot or production quantities, and concludes with delivery and comprehensive reporting, including complete analytical and process documentation. Each stage is carefully managed to maintain quality, regulatory compliance, and seamless transition from laboratory synthesis to full-scale production.
