Methylmorpholine

Part of speech: noun

Definitions

1. A heterocyclic organic compound consisting of a morpholine ring substituted with a methyl group, commonly used as a solvent or chemical intermediate in synthesis
2. A nitrogen-containing cyclic ether with a methyl substitution on the morpholine ring, employed in pharmaceutical and industrial chemical processes
3. An amine oxide featuring a morpholine framework bearing a methyl group, often utilized in chemical manufacturing and as a reagent in organic reactions

Etymology: Ludwig Knorr named morpholine in the belief that its ring was a fragment of morphine, the opium alkaloid he was studying. That turned out to be wrong: morpholine is not part of morphine's structure. The name stuck anyway, and it now describes a six-membered ring containing one oxygen and one nitrogen atom. "Methyl" comes from Greek "methy," meaning wine, and "hylē," meaning wood or matter. Chemists gave the name to the group because it was first obtained from wood spirit, the crude liquid distilled from wood. The prefix tells you that a methyl group, a single carbon with three hydrogens, has been attached to the ring. Its position on the ring determines the compound's specific properties, which is why chemists name the position as well.
