Usage

General Description

4,4-thiobis-2-butanone is a chemical compound commonly known as diacetyl monoxime, or simply DMO. It is a yellow crystalline solid with a strong odor and is primarily used as a reagent in analytical chemistry, especially in the detection of various metals. DMO is also used in the determination of nitrite and carbonyl compounds in water and other samples. It is non-flammable and stable under normal conditions, making it a useful and versatile chemical in laboratory settings. However, exposure to DMO can irritate the skin, eyes, and respiratory system, so proper safety precautions should be taken when handling this compound.
