About Top Science

Custom Synthesis

The customer provides literature methods or their own synthesis route in which all details (reaction times, solvents, temperatures, analytical data, purification methods, yields, etc.) are included. If you have no technical information, we can give an estimate after we carefully review it.

Our chemists' team will evaluate synthesis and determine whether to pursue the project. We will reply you usually in 48 hours. If so, we will provide an estimate of cost and delivery time. TOP Science honors its quoted price even if a project requires more work than anticipated. We will charge the client only for successful syntheses.
