Retiring Chemicalize Pro Services, Transitioning to Modern Solutions

Written by Chemaxon | 26 11 2025

We are retiring the Chemicalize Pro suite of services, with a final phase-out date of December 31, 2025.


This move is part of our strategic initiative to modernize our product portfolio and focus on more advanced, integrated solutions for the scientific community.


The retirement will affect all Chemicalize Pro services, including Hosted Catalog Search, Chemical Drawing, Compliance Checker API and Calculation API.


Current users will retain full access to Chemicalize Pro until their subscription term ends or until the December 31, 2025, retirement date, whichever comes first. Subscriptions will terminate automatically at the end of the term, requiring no action from customers.


For customers seeking to replace specific functionalities, we recommend the following products:

 

  • Marvin: A comprehensive solution for chemical drawing and visualization.
  • Calculators & Predictors: A powerful suite of tools for advanced property calculations and predictions.
  • Compliance Checker: Screening chemistry against controlled substance regulations at the click of a button.

 

To facilitate this change, our team is available to help customers evaluate alternative products and plan their migration. In case you have questions or need assistance, we encourage you to reach out for personalized guidance via email at sales@chemaxon.com.
