ChemSun provide custom synthesis of various scaffolds building blocks, reference compounds and novel reagents to serve pharmaceutical and biotech companies, universities and research institutions.

We have successfully and punctually completed over 3,000 individual compounds in complex multi-step processes (average eight steps each) and on scales ranging from a few milligrams to several kilograms; our success rate is over 95%. We once completed a custom synthesis project that took 34 synthetic steps and required 5 grams of the finished product. Our highly efficient and professional project management group and chemistry team hold the key to our consistent success. We consider organic synthesis to be an art; the creation of compounds is a function of the chemists’ knowledge, skill, creativity, motivation and hard working. Our chemists take great pride in their accomplishments.

We deliver not only compounds but also reliable, high quality organic synthesis service. Our customers expect rapid turnaround times on both the quotes and delivery of the product. As a general rule, we respond to new inquires within 48 to 72 hours after the initial screening of literatures. Once a project is underway, we provide each customer with a biweekly report updating the status of the synthesis project. This facilitates real-time feedback from customers. We listen carefully to customers’ concerns and needs and address each promptly and effectively.
