Eight specialized agents. One unified drug discovery platform.

Retrosynthesis Agent

AI-Powered Synthesis Planning

Starting from any target molecule, Rasayan maps every viable synthetic route to commercially available building blocks — with live vendor pricing, real-time availability, and estimated synthesis cost. One-step precursor mode finds shortcuts when you need the immediate precursor, not the full route. Multi-step mode plans complete pathways optimized for cost, risk, and patent clearance — in minutes, not weeks.

Reconfigure synthesis pathways on-the-fly by swapping or pinning intermediates — the route updates around your constraints
Every recommended step is backed by literature-cited protocols with specific reagent quantities, temperatures, and solvents
Pitfall warnings flag known issues before they cost you a failed experiment — with suggested fixes built in
Toxicity and process impurity predictions tied to each route, not just the final compound
Patent-cleared pathways flag IP-encumbered steps so you never walk into a dead end
Confidence scores at every step — data-driven route ranking based on precedent, not guesswork

The Knowledge Engine

The data the agents think with

Two layers of intelligence — the institutional memory of your organization, and the most comprehensive chemistry dataset ever assembled.

Your Data

Your organization has decades of answers. They're buried in documents.

Rasayan extracts, structures, and indexes everything — chemical structures, reactions, yields, equipment parameters, and failure modes — into a living knowledge base your team queries in plain language.

Ingests any format

  • Handwritten & printed lab notebooks
  • Patents, SOPs, IPR notes & regulatory filings
  • Process engineering & scale-up documents
  • Reaction reports, batch records & ELNs
  • Equipment logs, parameter sheets & failure reports

What gets extracted

Chemical structures

Every structure recognized and indexed as machine-readable SMILES — from scanned images, tables, or text

Reaction conditions

Temperature, solvent, catalyst, time, pressure — linked to every reaction step across every document

Yields & purity data

Parsed from tables, paragraphs, and handwritten notes — normalized and ranked across batches

Equipment parameters

Instrument IDs, settings, calibration records, and lot numbers — mapped to outcomes

Failure records

Root causes, deviations, corrective actions — the institutional memory that prevents repeating mistakes

Regulatory signals

Mutagenicity flags, degradation markers, ICH-relevant observations — surfaced automatically

Our Data

The largest chemistry corpus ever assembled for AI.

105 specialized AI models. Not fine-tuned on generic data. Not prompted. Trained from scratch on the most comprehensive chemistry dataset ever compiled — reactions, patents, compounds, and molecular space at a scale no other platform matches.

This is the foundation every agent reasons over — from retrosynthesis route planning to patent freedom-to-operate analysis.
