Thioacetone is an organosulfur compound belonging to the -thione group called thioketones, with a chemical formula (CH3)2CS. It is an unstable orange or brown substance that can be isolated only at low temperatures. Above −20 °C (−4 °F), thioacetone readily converts to a polymer and a trimer, trithioacetone. It has an extremely potent, unpleasant odor, and is considered one of the worst-smelling chemicals known to man. high temp servicesWebPlease choose one of the options below to gain access to the full monograph: Log in using your subscriber credentials; Log in via your home institution how many dewormers do puppies get
