For companies and labs
Chemistry drawing for your company, free for commercial work
Athanor is free for commercial work and publication, opens and saves ChemDraw CDX and CDXML both ways, and runs in the browser and on Windows. Your team keeps working with partners on ChemDraw, and nobody needs a seat license to draw.
ChemDraw files, both ways
Open CDX and CDXML as they are and save them back, with 21 journal document styles including ACS Document 1996. Convert single files in the browser with the ChemDraw converters, and see how ChemDraw’s shortcuts carry over.
Retrosynthesis with hazards
With a free arbastro account, Athanor plans routes back to buyable starting materials as you draw, and shows sourced hazards for every compound along a route. Every AI-generated structure and route is screened against the Chemical Weapons Convention schedules and the Australia Group list.
In your pipelines and tools
Assistants and scripts can use Athanor’s engine through its free MCP server, and your ELN or registration system can embed the editor with one script.
For a whole team
arbastro Suite Ultra covers a school, department, lab or company: $99.99 a month, or $999.99 a year. Compare the plans.
