What We Do
So, briefly: who are we?
Chemaxon is a leading cheminformatics company, with headquarters in Budapest, Hungary and offices in the US and Switzerland
And what do we do?
We provide chemical software development platforms mostly for the biotechnology and pharmaceutical industries - but any chemist might find us useful.
Why do our users prefer us?
Because we are known for our rapid and high quality technical support, we develop our tools together with our users (the reason we have good quality software); and because we support academic research and teaching like no one else in the industry!
All right, so exactly what are we good for?
Well, among many other things, you can draw & view chemical structures with Marvin Suite; manage and search your compounds with JChem tools; search your database in Excel or in our Instant JChem interface; perform a variety of calculations and predictions; cluster, screen, fragment or synthesize your compounds virtually and deal with Markush structures.
That's it really in a nutshell. If you are interested, contact us or post a message here.
