Chemical Availability Search (ChASe)

ChASe is a data source that enables researchers to search across numerous suppliers to source and compare chemicals for use in their projects. ChAse can be searched using the PSDI Cross Data Search service, where it can be searched using the dedicated Find Chemical Product Availability tab in the Cross Data Search. You can use this view to search ChASe by substance name, Chemical Abstracts Service register number (CAS), or another identifier such as an InChI string, InChI key, and SMILES.

To find out more about how to search ChASe using the PSDI Cross Data Search Service, see Searching Chemical Availability (ChASe).
