Magnesium perchlorate is a strong oxidizing agent. Magnesium perchlorate has been found to be an efficient catalyst for the synthesis of imines and phenylhydrazones by the reaction of carbonyl compounds with amines and phenylhydrazine in high yields at room temperatures and in short times. Magnesium perchlorate has being shown to be a radiosensitizer in in vitro radiolysis of nucleotides.

Ochratoxin A—a toxin produced by Aspergillus ochraceus, Aspergillus carbonarius, and Penicillium verrucosum—is one of the most-abundant food-contaminating mycotoxins. It is also a frequent contaminant of water-damaged houses and of heating ducts. Human exposure can occur through consumption of contaminated food products, particularly contaminated grain and pork products, as well as coffee, wine grapes, and dried grapes. The toxin has been found in the tissues and organs of animals, including human blood and breast milk. Ochratoxin A, like most toxic substances, has large species- and sex-specific toxicological differences.
