What is Choline hydroxide?
Chemical properties
clear light yellow viscous solution
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).
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.
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.
