The In-Silico Pharmaceutical Platform

Automate pharmaceutical risk and CMC decisions. Degradation, toxicology, stability, impurity limits and method design — in seconds.

MolWard unifies eleven validated engines — forced-degradation profiling, ICH M7 toxicology, ICH Q1E and accelerated stability, ICH Q3 impurity limits, dissolution f2 equivalence, chromatography method scouting, QbD design-of-experiments with ICH Q8 design space, everyday USP/ICH QC calculators, and dose- and exposure-limit calculators — moving risk and CMC decisions to the earliest stages of in-silico design.

The Problem We Solve

De-risk your pipeline before the lab

Traditional development relies on expensive, late-stage empirical testing. Unforeseen liabilities — a mutagenic impurity, an oxidative degradant, a shelf-life that fails at month 12 — can trigger clinical holds and cost millions. MolWard shifts risk assessment to the earliest stages of design, with rigorous, transparent chemistry.

Read the science behind MolWard

Unforeseen nitrosamine formation

"Cohort of Concern" impurities now carry intake limits as low as 18 ng/day.

Shelf-life that fails late

An out-of-trend assay pull at month 12 can derail an IND timeline and trigger OOS investigations.

Structural alerts found too late

Mutagenic toxicophores discovered in the lab cost millions to remediate.

Our Platform

Eleven engines. One automated workflow.

From forced-degradation and stability evaluation to mutagenicity and impurity limits, dissolution equivalence, chromatography method scouting, QbD design-of-experiments and ICH Q8 design space, the everyday USP/ICH QC calculators, and the dose- and exposure-limit calculators clinical and CMC teams reach for daily — unified in one defensible, transparent pipeline.

DegradationICH Q3A/B

Computationally simulate hydrolytic, oxidative, photolytic, and thermal stress. Map complete degradation pathways and generate MS fragmentation profiles to accelerate SIM development.

  • Dynamic nitrosamine CPCA & AI limits
  • Structural read-across with literature citations
Explore Toxicology

StabilityICH Q1ENew

Two modes: statistically evaluate long-term data per ICH Q1E (95% LCB shelf-life, OOT flagging), or predict shelf-life from accelerated stress data with a moisture-modified Arrhenius fit. Every run generates a signed-off-ready PDF report.

  • 95% LCB shelf-life projection vs. LSL (ICH Q1E)
  • Accelerated Arrhenius + humidity shelf-life prediction
  • OOT flagging, AI-assisted interpretation + PDF
Explore Stability

Impurity LimitsICH Q3

Enter a single maximum daily dose and route to instantly generate all applicable ICH Q3 thresholds — organic impurities, residual solvents, elemental impurities, and extractables AET.

  • Q3A(R2) & Q3B(R2) reporting, ID & qualification thresholds
  • Q3C(R9) solvent PDEs & Q3D(R2) elemental PDEs by route
  • Q3E / USP <1663> analytical evaluation threshold (AET)
Explore Impurity Limits

Dissolution Equivalencef2 / FDA SUPAC

Compare two dissolution profiles the way a regulator does: the f2 similarity and f1 difference factors, the 85% rule and RSD eligibility checks, and a bootstrap 90% CI of f2 for high-variability products.

  • f2 & f1 with automatic 85% rule and RSD guardrails
  • Bootstrap lower-90% CI of f2 (5,000 resamples)
  • Weibull / first-order / Higuchi / Korsmeyer-Peppas fits
Explore Dissolution Equivalence

Chromatogram PredictorRP-HPLC

Predict reversed-phase chromatograms and elution order from SMILES, scout columns / mobile phases / pH, and get a recommended detection wavelength — straight from a degradation run or a custom molecule list.

  • Ranks 150 conditions by critical-pair resolution
  • 5 columns × 6 mobile phases × 5 pH values
  • Recommended UV detection wavelength
Explore Chromatogram Predictor

Column SelectivityHSM / Fs

Compare reversed-phase HPLC columns objectively with the published Hydrophobic-Subtraction Model — rank equivalents and flag non-interchangeable columns before you re-validate a method.

  • Five-term selectivity model (H, S*, A, B, C)
  • Column-comparison distance (Fs) ranking
  • Analyte-aware equivalence for ionizable compounds
Explore Column Selectivity

QbD DoE & Design SpaceICH Q8New

Design an experiment, fit a response-surface model, and map the ICH Q8(R2) design space — the multivariate region where every response stays in specification — with a Monte-Carlo edge of failure. The QbD workflow scientists return to for every formulation, process or method they optimize.

  • Factorial, Plackett-Burman, Box-Behnken & central-composite designs
  • Response-surface model, ANOVA, lack-of-fit & effect Pareto
  • Design space + Monte-Carlo edge of failure + audit-ready PDF

The transparency regulatory agencies demand

Every MolWard prediction is backed by Principal Component Analysis (PCA) for Applicability Domain verification and SHAP feature interpretability — so you can prove exactly why a classification was made. Every Q1E interpretation is guard-railed to the analyzer's computed numbers and a code-controlled list of real ICH citations.

01

Applicability Domain (PCA)

Every prediction is verified against the chemical space of the training data.

02

SHAP interpretability

Feature attributions explain the structural drivers behind each result.

03

Guard-railed interpretation

AI drafts read only computed facts and cite only allow-listed ICH guidelines — flagged for expert sign-off.
