Morpholine is an organic chemical compound. This heterocycle features both amine and etherfunctional groups. Because of the amine, morpholine is a base; its conjugate acid is called morpholinium. For example, treating morpholine with hydrochloric acid makes the salt morpholinium chloride.
Morpholine is widely used in organic synthesis. For example, it is a building block in the preparation of the antibiotic linezolid and the anticancer agent gefitinib
In research and in industry, the low cost and polarity of morpholine lead to its common use as a solvent for chemical reactions
Morpholine is used as an aid by the dissolution and emulsifing of shellac, which is used as a wax for fruit coating.
Morpholine derivatives used as agricultural fungicides in cereals are known as ergosterol biosynthesis inhibitors
