Cholesteryl nonanoate
From Wikipedia, the free encyclopedia
Cholesteryl nonanoate, also called cholesteryl pelargonate, 3β-cholest-5-en-3-ol nonaoate or cholest-5-ene-3-β-yl nonanoate, is an ester of cholesterol and nonanoic acid. It is a liquid crystal material forming cholesteric liquid crystals with helical structure. It has the appearance of white crystals with melting point at 77-82 °C. It is insoluble in water.
Its CAS number is [] and its SMILES structure is C[C@H](CCCC(C)C) [C@H]4CC[C@@]3([H]) [C@]2([H])CC=C1C[C@@H] (OC(CCCCCCCC)=O)CC[ C@@](C)1[C@]([H])2 CC[C@@]34C. Its EINECS number is 214-658-3. Its chemical formula is C36H62O2.
It forms beautiful spherulite crystals.[1]
It is used in some hair colors[2], make-ups, and some other cosmetic preparations[3]. It is also used in some pleochroic dyes and together with eg. cholesteryl oleyl carbonate and cholesteryl benzoate in some thermochromic applications[4].
It can be also used as a component of the liquid crystals used for liquid crystal displays.
