LCP - Lipidic Cubic Phase
Purity >99%
Host lipid for LCP Lipidic Cubic Phase
Monoolein forms a LCP Lipidic Cubic Phase when mixes with protein solution

Synonyms 1-(cis-9-Octadecenoyl)-rac-glycerol, rac-Glycerol 1-monooleate, DL-α-Monoolein, Glyceryl cis-9-octadecenoate, 1-Oleoyl-rac-glycerol, 9-monoolein, 9-monooctadecanoin, 9.9 MAG

Formula C21H40O4 Linear Formula CH3(CH2)7CH=CH(CH2)7COOCH2CHOHCH2OH
Formula Weight (Mr) 356.50
CAS Number [111-03-5]
EC Number 203-827-7
Beilstein Registry Number 1728976
MDL Number MFCD00042735
PubChem Substance ID 24897178
Appearance (starting material) Clear colorless liquid to white waxy solid at room temperature
Purity >99% by Thin Layer Chromatography (TLC)
Gas liquid chromatography > 99% on methyl ester
Thin layer chromatography shows only the monoglyceride moiety present
Type Non-ionic
Melting Point 35 degrees Celsius
Original source Sunflower oil
Infrared spectrum Conforms to structure

Store at 0 degrees Celsius or colder. Unopened vial best if used within 24 months of receipt. Once opened, best if used within 6 months. To enhance the stability of remaining material after the vial is opened, gently purge the vial with an inert gas such as nitrogen or argon, which will remove oxygen which can cause oxidation of the Monoolein.

Soluble in chloroform (50 mg/ml). Soluble in Hexane and can be crystallized from Hexane. In water, Monoolein tends to form a gel or emulsion.
