Dear Rahmani

Please check out this tool: https://www.metabolomicsworkbench.org/databases/refmet/browse.php

Sure! Use ChemRICH: http://chemrich.fiehnlab.ucdavis.edu/class.html and their paper: https://www.nature.com/articles/s41598-017-15231-w

Thanks,

Biswapriya Biswavas Misra Albert Batushansky thank you that was helpfull

I suggest using a ClassyFire https://cfb.fiehnlab.ucdavis.edu/

PUTMEDID https://github.com/RASpicer/MetabolomicsTools/wiki/PUTMEDID%E2%80%90LCMS

this tool gives both putative annotations and biological class

Try Classyfire webserver from Wishart lab U will need just the smiles or inchi as input
