Impurity Control Working Group

The mission of the Impurity Control WG was to formulate an industry position for organic impurities from fermentation and semi-synthetic derived drug substance, peptide and peptide conjugates, and antibody-drug conjugates.


The group had two active subgroups.  The first was focused on the small molecule impurities in anti-body drug conjugates and the second was focused on impurities as they relate to oligonucleotides.
