What Molecules editors screen for
The signals Molecules rewards before the first reviewer
The readiness scan checks your manuscript against these first.
Novel molecular structure or synthesis with demonstrated characterization
Present novel compounds, synthesis routes, or interesting molecular modifications. Provide rigorous characterization: NMR, mass spectrometry, melting points, purity. For natural products or bioactive compounds, include structure elucidation and spectroscopic data.
Biological activity assessment when applicable
For medicinal or natural product chemistry, assess bioactivity. Test compounds in cellular or biochemical assays. Provide structure-activity relationship (SAR) analysis showing how molecular structure affects biological function.
Synthetic methodology advantages clearly demonstrated
If proposing synthesis method, show advantages: improved yield, shorter steps, greener conditions, lower cost, broader substrate scope. Compare with existing methods. Incremental improvements need clear justification.
Common Molecules rejection patterns
Named failure modes the scan looks for
These are patterns Molecules editors flag in initial triage. The free preview surfaces when your manuscript shows them.
Reporting compound synthesis without sufficient characterization data
NMR, mass spectrometry, melting point, and purity data are minimum expectations. Incomplete characterization suggests careless work and raises reproducibility concerns.
Proposing compound without clear structural novelty or purpose
Incremental structural variation (adding methyl group, changing substituent position) without clear motivation or demonstrated novelty is weak. Show why this structure matters.
Bioactivity testing without positive controls or dose-response curves
Proper bioactivity assessment requires dose-response curves, positive controls, appropriate statistical analysis. Single-concentration activity screening is insufficient.
Common questions about Molecules submissions
Does the scan understand Molecules's editorial standards?
The readiness scan is calibrated to Molecules's scope and review signals. It estimates desk-rejection risk against known triage patterns, flags where your manuscript sits against journal fit, and surfaces the specific reviewer objections most likely to come up.
How long does the Molecules scan take?
The free preview takes about 1-2 minutes once you upload. If you want the Full Review with verified citations and section-by-section critique, it is delivered as a DOCX in about 30 minutes, after hundreds of parallel frontier-model LLM calls per review.
Is my manuscript safe?
Yes. Uploads are encrypted in transit, not used to train any AI model, and deleted after analysis. No human reads your manuscript on the AI path.
