  5. 5.  We will deliver the requested products on time and provide all characterization data.
  6. 6.  If the synthesis cost exceeds $5,000, we’d bill 40% upfront as material and initiation cost.
  • Medicinal chemistry to modify the lead compound (project-based or FTE-based)
  1. 1.  Email us ([email protected]) your Confidential Disclosure Agreement (CDA) or use our standard CDA to protect your IP rights.
  2. 2.  After execution of CDA, email us the lead compound’s structure and specific plan for the lead optimization. If there are established synthesis procedures, it’d be helpful and may affect the quote pricing.
  3. 3.  If you need any inputs from our experienced medicinal chemistry leader, or you would like XcessBio to carry out the lead optimization independently, we will have a conference call first to understand the details.
