Organomercury reagents are synthetically useful in additions across alkenes to provide oxygenated functionalities. Within the diversity of organometallics offered by Sigma-Aldrich, organomercurials have several applications in developing vaccines, antifungal reagents, topical antiseptics and as analytical standards. Due to their high affinity with thiols, mercuric acetates have also shown to be potent inhibitors of enzymatic processes.
