C15 reaction intelligence · 30 rounds

Trace every route
back to origin.

Enter a node ID or a C15 structure as SMILES, or draw the target structure directly. The explorer validates it, finds an exact or closest database record, and ranks supported reaction routes in the selected direction.

How ranking works

Shorter routes.
Lower barriers.
Clear provenance.

  1. 01

    Validate & matchResolve node IDs directly, or standardize a SMILES and progressively compare the full structure, charged unsaturated scaffold, neutral unsaturated scaffold and saturated skeleton.

  2. 02

    TraceWalk incoming edges backward to Round 1 or outgoing edges forward to terminal nodes, pruning cycles and paths deeper than 30 steps.

  3. 03

    RankPrioritize fewer scored hops, lower summed barriers, and more stable matched endpoints. Near-degenerate 1/5 or 2/4 alternatives are resolved by their intermediate energies. Resonance-form steps have zero barrier and do not add to scored length.
