Dear Colleagues, 

I concur with the need for more clarity around sources of data reported in SDSs from manufacturers and chemical suppliers. Requiring references is the norm in published scientific literature, why not this standard of quality and traceability in SDSs as a key source of information?

Just a note about the Safety & Hazard information in PubChem - this is sourced from many different agencies and other entities. These sources are documented under each entry with a link back to the original source. 

The corrosive GHS symbol included for Pentadecafluorotoctanoyl chloride is from ECHA, for example. Specifically the source is the ECHA C&L inventory database, which compiles classification and labelling notifications from a number of companies as reported to ECHA per the CLP criteria (EU regulation).  

https://pubchem.ncbi.nlm.nih.gov/compound/Perfluorooctanoyl-chloride#section=GHS-Classification
https://echa.europa.eu/information-on-chemicals/cl-inventory-database/-/discli/details/62650

PubChem is a service from the National Library of Medicine that provides information from other authoritative sources as reported. The motivation is to provide a starting point and where to link to find further information. It is incumbent upon the user to determine what information and source is relevant for their needs. PubChem is not an official classification entity for GHS or any other status of chemical substances. 

I hope this may help generally. As a volunteer curator with PubChem, I am happy to have ideas for additional data and information sources. 

Best wishes, 
Leah

That would be a great topic to take up in a CHAS chat. We did begin this discussion in the March CHAS chat this year on Quality Data For Safer Experiments.q You can see the notes from this session at
http://dchas.org/2021/03/11/quality-data-for-safer-experiments/

However, a more focused discussion on assessing the fit of a SDS to answering a lab safety question would be a good topic for a group discussion. Do we have any volunteers to lead this discussion?

Thanks for this suggestion!
