Overview
Athanor by arbastro is a free chemistry drawing app for students, educators and researchers. It opens and saves ChemDraw CDX and CDXML files, predicts products as you draw, plans syntheses back to buyable starting materials, and animates mechanisms.
What it is
Athanor is a chemical structure editor made by arbastro. It runs in the browser and as a Windows desktop app, and the editor is free. It is not related to the structural biology software of the same name from Athanor Lab.
Draw a reaction and Athanor predicts the product; ask for a route and it plans a synthesis back to starting materials you can buy, with hazards marked. Mechanisms can be drawn with curly arrows, checked step by step and animated. It reads and writes ChemDraw CDX and CDXML, MOL, SDF and SMILES, and exports in journal styles such as ACS Document 1996.
Who it is for
Students get the editor, a compound library of 962 sourced compounds, flashcards and self-grading problem sets. Educators build problem sets that grade arrow-pushing answers step by step. Researchers get journal-ready figures, compound information with every value sourced, and the arbastro Intelligence models for product prediction, retrosynthesis and NMR.
arbastro Suite members get more AI use in Athanor along with the Suite perks in every other arbastro app.
