This is a template for all chemists contributing lab book entries to the OSM project. For general guidelines on how to post please follow this link.

For a model OSM ELN Chemistry Post, see here <- Link needed.

1. Title

The title of your post should be along the lines of "Synthesis of [insert chemical name]" and should also included a chemist identifier featuring the chemist initials followed by the reaction number a dash and then a number corresponding to how many times the reaction has been repeated. e.g

"Synthesis of 1-(4-fluorophenyl)-2,5-dimethyl-1H-pyrrole (AEW 1-3)"

If this is the first reaction AEW performed and is the third time AEW has done the reaction. Keeping this format makes the entries much easier to search.

N.B. The post should be saved as a draft until the reaction is about to be started.

2. Summary

A one or two line summary of the reason for carrying out the reaction is very helpful when scrolling through the ELN.

When the reaction is complete, a short comment as a conclusion is very useful and makes it much quicker to read through the ELN.

Also try to include links to starting materials or similar/repeat posts. For compounds that require further characterisation, a comment here is a great help for project organisation.

3. Hazard and Risk Assessment

This is the most important document on your post. A comprehensive risk assessment should be performed prior to commencing your reaction. Please follow your institutional guidelines and communicate with health and safety representatives at your school. 

4. Reaction Scheme

A reaction scheme saved as a PNG and uploaded should be posted close to the top of the blog entry featuring all reagents and conditions. Any amendments should be noted in the text.

5. Tabulated Chemicals and Quantities

A record of mass, moles, densities and volumes etc for chemicals used is a great tool for anyone repeating your experiment. Either use the limited table function in labtrove or save excel tables as png images and import.

6. Procedure

A detailed chemical procedure (journal standard) should be included for all experiments. Feel free (in fact we encourage it) to add extra details about your reaction and pictures or videos of your observations. The more information the better. Important: Don't worry if you make mistakes, no matter how daft they may seem. The purpose of this ELN is to be honest and transparent. If you drop your reaction, just write that down - we all make mistakes and this is an open document for an open and understanding team of scientists.


If you record a TLC, NMR, IR or any other measurement upload a picture or a file containing your raw data. Please feel free to also upload processed data such as pdf, but remember to always post the raw data too. This means that other scientists can analyse and use your data.

8. Write up Data

When you have collected some or all of your data, write it up as you would for publication. This means that when the time comes for publication, noone will have to repeat your results and so you will be credited as an author for your contribution. It also means that other members of the project or external contributors can proofread your data in real time, and add a comment to say that they agree with your data.

9. References

Include references, links and/or DOIs to any publications that you followed for your reaction or for data comparison.

10. InChi Strings

In order for the ELN to be machine searchable it is important to include InChi Key for reagents and products. Just paste those in as text at the bottom somewhere.


Good luck with your reactions and thanks for joining the OSM team.
