3-Hydrazinobenzoic Acid is a derivative of 4-hydrazinobenzoic acid, a component of the mushroom Agaricus bisporus, which is carcinogenic to rodents. 4-Hydrazinobenzoic Acid also has antioxidant properties, and as an additive to inhibit the oxidation of Sn2+, it improves the optoelectronic properties of Sn-Pb alloy chalcococite[1-2].
