Ammonium Sulfide Solution, 25mL

Ammonium sulfide solution (aqueous ammonium sulfide) is a 20% solution in water. Ammonium sulfide is an inorganic salt with a sulfurous odor, which is commonly used in the food industry as a flavoring agent. The influence of ammonium sulfide treatment on (100)GaAs (gallium arsenide) surfaces has been studied by X-ray photoelectron spectroscopy (XPS) and reflection high-energy electron diffraction (RHEED). Its potential as an alternative to hydrogen sulfide for the transformation of activated amides to thioamides by thiolysis has been investigated. The reaction of ammonium sulfide with 3-hydroxy-2-butanone over a range of temperature has been reported to form various flavor compounds. Ammonium sulfide is a reagent that is used in large scale applications such as textile manufacture, the production of photographic developers, the application of patina to bronze, and trace metal analysis. Additional applications of this compound include cell culture, organic chemical synthesis, and immunohistochemistry. It is also used in continuous culture of Saccharomyces cerevisiae. It has been utilized in a double staining technique for visualization of astrocytes and microglia from brain sections and astroglial cell cultures.
