General description

Diethyl ether (also known as ethyl ether or ether) is a laboratory solvent. It is a desirable solvent for oils, fats, waxes, perfumes, dyes, resins, hydrocarbons, and gums. It is also used as fuel and to synthesize other chemical compounds. DEE is widely employed as a solvent for Grignard synthesis.

Application

Diethyl ether is used as a solvent in the 3D-printed reaction ware device for chemical synthesis.

Hypoxia-inducible factor-1 alpha (HIF-1α) is considered a global regulator of cellular metabolism and innate immune cell functions. Intracellular pathogens such as Leishmania have been reported to manipulate host cell metabolism. Herein, we demonstrate that myeloid cells from myeloid-restricted HIF-1α-deficient mice
