What is Choline hydroxide?

Chemical properties

clear light yellow viscous solution

The Uses of Choline hydroxide

Choline hydroxide is used as a precursor molecule for the neurotransmitter acetylcholine, it is involved in several functions including muscle and memory muscle control. It was used as a basic catalyst for aldol condensation reactions.

The Uses of Choline hydroxide

Choline hydroxide solution has been used in the synthesis of choline hexafluoroacetylacetonate that can be used as an extractant along with bis-(trifluoromethylsulfonyl)imide ionic liquid for the homogeneous liquid-liquid extraction of neodymium(III).

Definition

An amino alcohol,CH₂OHCH₂N(CH₃)₃OH. It occurswidely in living organisms as aconstituent of certain types ofphospholipids– the lecithins andsphingomyelins– and in the neurotransmitteracetylcholine. It issometimes classified as a memberof the vitamin B complex.
