Also referred to simply as thiosulfuric acid, ammonium thiosulfate is a common chemical compound used in the field of photography, various forms of chemical analysis, and other industrial purposes. It is marked by a distinct scent of ammonia. The compound can be found in a white crystalline or liquid form.
Ammonium thiosulfate has a molecular weight of 148.195 g/mol and a complexity of 82.6.
The monoisotopic mass and exact mass are both 147.998 g/mol. It also has a heavy atom count of seven, a hydrogen bond acceptor count of four, and a hydrogen bond donor count of four. The compound has a melting point of 302° F (150° C) and is 64% water soluble at 68° F. It is also slightly solubility in acetone, but completely insoluble in alcohol and ether.
It is often used as a desiccant and defoliant in plants that produce crops like soybean, cotton, alfalfa, and cotton. Ammonium thiosulfate’s other uses include desulfurizing flue-gas and the conversion of cellulose to hydrocarbons. Using ammonium thiosulfate on corn and other consumable crops has grown over time since the sulfur helps in producing healthy plants.
