The Comparative Toxicogenomics Database (CTD) presents scientifically reviewed and curated information on chemicals, relevant genes and proteins, and their interactions in vertebrates and invertebrates. It integrates sequence, reference, species, microarray, and general toxicology information to provide a unique centralized resource for toxicogenomic research. The database also provides visualization capabilities that enable cross-species comparisons of gene and protein sequences.

This resource is a provider. This means that while it may have its own prefix, it actually reuses the identifiers provided by the mesh prefix. For all use cases, you should use mesh instead of ctd.chemical.

^[CD]\d+$

Example Local Unique Identifier
D001151   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from CTD Chemical should match this regular expression:
^ctd.chemical:[CD]\d+$

Example CURIE
ctd.chemical:D001151
Metaregistry

The metaregistry provides mappings between the Bioregistry and other registries. There are 3 mappings to external registries for ctd.chemical.

Registry Name Metaprefix External Prefix
Identifiers.org miriam ctd.chemical
