The PubChem Classification Browser allows you to browse the distribution of PubChem data among nodes in the hierarchy of interest, thereby providing an aggregate view of PubChem data. It also allows you to search for PubChem records annotated with the desired hierarchy/term, providing a powerful way to quickly find the subset of PubChem records.
