The use of dangerous chemicals in the laboratory can lead to major risks. To prevent related disasters, hazardous reaction incident information must be shared across the global research community. With the CAS Chemical Safety Library:

Search

Learn about hazardous reaction information before you head to the laboratory. Search by CAS Registry Number®, chemical name, SMILES, and more.

Contribute

Help make the library even more valuable to other researchers by submitting your hazardous reaction incident information.

Download

Integrate hazardous reaction information from the library with your internal workflows and knowledge bases.

Your gateway to lab safety

The CAS Chemical Safety Library is a repository for the scientific community to capture and confidentially share hazardous reaction information from real-world laboratory experiences to reduce and prevent incidents. Information in the library is publicly available and uploaded to PubChem.  

The repository is overseen by an advisory panel made up of experts from CAS, ACS, and academic, industry, and non-profit organizations worldwide.
