Welcome to ChemData
ChemData is our in-house data management system. We are still developing client access to ChemData. In the meantime, we have provided a free tool to check the consistency of SEDDs provided for use with ChemData.
ChemData SEDD Screener
This free tool checks SEDDs for general conformance with ADS’s ChemData Specifications. This tool runs in your browser, maintaining confidentiality of your client’s data (no upload necessary).
ChemData SEDD Specifications
This page provides additional guidance and specifications particular to our data management system, as well as clarification for some requirements that are ambiguous in the EPA SEDD Specifications.
