Unfiltered Depositor-Provided Chemical Synonyms for Substance Records in PubChem

This gzipped text file contains a list of all (live) substance records in PubChem with their "unfiltered" depositor-provided chemical synonyms, downloaded from PubChem in June 2017. Each line has a Substance ID (SID) and its chemical synonym, separated by a tab. The SID-synonym pairs in this file were used in the paper “PubChem Synonym Filtering Process Using Crowdsourcing” by Sunghwan Kim et al., published in the Journal of Cheminformatics (https://doi.org/10.1186/s13321-024-00868-3). The up-to-date version of this file can be downloaded from the PubChem FTP Site (https://ftp.ncbi.nlm.nih.gov/pubchem/Substance/Extras/).
