ACD/I-Lab Structure-based predictions
How does ACD/I-Lab work?
Predictions are made using algorithms developed by ACD/Labs, based on chemical
structures entered by:
Searching the chemical dictionary of >36,000 names and >8,900 chemicals
Drawing into the I-Lab interface or pasting a structure from ACD/ChemSketch
Uploading a molecular structure file (.mol, .skc, .cdx, .sk2)
Typing or pasting a SMILES string
NMR spectra prediction
ACD/I-Lab predicts NMR spectra (1H, 13C, 15N, 19F, 31P), and links each signal with the
corresponding atoms of the chemical structure.
How do I access ACD/I-Lab?
ACD/I-Lab is provided to the UK academic community via the Royal Society of
Chemistry-hosted Chemical Database Service at cds.rsc.org. ACD/I-Lab has been
developed by ACD/Labs (Advanced Chemistry Development, Inc.)
Access is authenticated by UK academic IP address via ilab.cds.rsc.org. If working

ARChem Synthetic Route Planner
at the Chemical Database Service
What is ARChem?
ARChem is an online tool for chemists who
want synthetic routes to organic molecules.
It allows the user to:
Generate ideas for a total synthesis of a
target molecule.
Propose routes leading from compound A
to compound B.
Look at the possibilities from commercially
available starting materials.
Suggest alternative synthetic routes and
strategies.
Take into account material costs and
yields.
How does ARChem work?
ARChem uses reaction databases to derive synthetic rules which inform the
retrosynthetic analysis of a target molecule.
Reaction rules are extracted algorithmically from a reaction database such as
Methods in Organic Synthesis.
The search generates full synthetic schemes, rather than individual steps.
Synthetic steps are linked to literature examples where possible.
To allow the user to navigate the search results, tools are provided to apply
constraints and thresholds in terms of yield, price and economy.

ARChem Synthetic Route Planner
What can I do with the results?
ARChem is a web-based application and all searches are submitted, and the results
viewed and analysed in the browser.
The user then navigates through the solutions space, finds paths of interest and
may expand the analysis or focus on more challenging regions of the target.
The results can be analysed and filtered:
Optionally designate breakable and unbreakable bonds
Pick starting materials to be used
Set synthetic depth
Filter by starting material cost
How do I access ARChem?
ARChem is provided to the UK academic community via the Royal Society of
Chemistry-hosted Chemical Database Service at cds.rsc.org. ARChem has been
developed by SimBioSys Inc., and is available at cds.rsc.org/archem
Access is authenticated by IP address, and registration is required for each user of
ARChem. A quota of searches is provided based on the size of the institution.

How do I identify chemical structures in a webpage?
Chemicalize is a public web resource which identifies chemical structures in
webpages and other text using ChemAxon's Name to Structure parsing. Structure
based predictions and a substructure/similarity search interface are provided.
The Webpage viewer identifies chemical structures mentioned on the page, and
indicates their prevalence.
Chemicalize can also be used to identify chemical structures in pdf documents.
What do I do with the results?
Chemical structures mentioned in a webpage can be downloaded as:
