Satratoxin-H, a trichothecene mycotoxin, is a naturally occurring mold byproduct of Stachybotrys chartarum which is toxic to humans and animals. The clinical condition it causes is known as Stachybotrotoxicosis. It is related to the mycotoxin T-2, but unlike T-2 has not been reported to have been used as a biological weapon. Satratoxin-H is almost completely insoluble in water, but is easily soluble in lower alcohols and polar solvents such as ethanol, methanol, isopropanol (rubbing alcohol), acetone and chloroform. Satratoxin-H is not officially classified as a chemical weapon. Satratoxin-H has little effect on bare skin, and does not blister in the way many chemical weapons do. However, upon sensitive surfaces (eyes, interior of mouth or nose), it can irritate the skin or cause a rash. The toxicology of satratoxin-H shows that it has an LD50 for mice of 1.0-1.4 mg/kg, upon injection.
