Bench-ready in days
Routes are predicted before they are run, so a bench-ready procedure arrives in days instead of months of retries.
The Interactive Virtual Reactor predicts a route's yield, cost, and impurities before the first flask.
Chemists lose up to six months per molecule to routes that looked right on paper and failed in the flask. Around 40% of first attempts fail. The retries are the expensive part.

Electrons rearrange, bonds form and break, barriers are crossed. The Chemistry World Model computes that physics from first principles. Not from precedent.

Evaluate routes, compare conditions, and optimise pathways before a single physical experiment. The lab becomes the place for confirmation, not exploration.

Every prediction rests on computed chemistry: kinetics, thermodynamics, quantum descriptors, and traces back to its reasoning. Routes that would fail die on screen.
Search tools stop at what has been reported.
Chemstack evaluates impurities, waste, cost, and IP risk before it's run on the bench.
Impurity prediction

Side products and carry-over impurities flagged per route, before they appear in your HPLC.
What changes in a chemist's week: routes ready in days, one experiment worth running, and one workspace.
Routes are predicted before they are run, so a bench-ready procedure arrives in days instead of months of retries.
12,648 candidate routes narrowed to the one experiment worth running, with yield and cost attached.
Routes, runs, results and decisions for the whole campaign in one shared space, with every change recorded.
Pharmaceuticals, agrochemicals and specialty chemicals. The same physics, run on every one of them.
Chemstack is built for the people who find those routes.
Crystallography, process chemistry and machine learning, from people who still run the molecules through it themselves.
