Hazard Information | Back Directory | [General Description]
White crystalline powder. | [Reactivity Profile]
1-OCTACOSANOL(557-61-9) is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides. | [Air & Water Reactions]
Insoluble in water. | [Fire Hazard]
Flash point data for this chemical are not available; however, 1-OCTACOSANOL is probably combustible. | [Chemical Properties]
white crystals or powder | [Occurrence]
Octacosanol is developed from wheat germ, sugar cane, or vegetable waxes. | [Uses]
A 28-carbon primary fatty alcohol commonly found in the epicuticular waxes of plants. It has shown protective effects against parkonsonism and due to its excellent tolerability and non-toxicity, octacosanol may be a promising agent for PD treatment. | [Definition]
ChEBI: A long-chain primary fatty alcohol that is octacosane in which a hydrogen attached to one of the terminal carbons is replaced by a hydroxy group. | [benefits]
1-octacosanol is a straight-chain aliphatic 28-carbon primary fatty alcohol used as a nutritional supplement. This high-molecular-weight organic compound is the main component of a natural product wax extracted from plants. 1-octacosanol is reported to possess cholesterol-lowering effects, antiaggregatory properties, cytoprotective use, and ergogenic properties. It has been studied as a potential therapeutic agent for treating Parkinson's disease. | [Synthesis]
To a solution of octacos-11-en-1-ol (400 mg, 0.98 mmol) in THF (40 mL), 10% of Pd on charcoal (50 mg) was added and poured into a Parr reactor. The reduction was carried out at 80 ℃ and 35 bar H2 under stirring for 4 h. Similar results were achieved when the reaction was performed in a special US reactor (21.2 kHz) that works under pressure (Danacamerini – Torino); the reaction was carried out at 40 ℃ and 6 bar H2 for 3 h. In both cases, after filtration on a celite pad and evaporation under vacuum, a crude product was purified by flash chromatography using hexane: ethyl acetate 19: 1 as eluent. 1-Octacosanol was obtained as a white powder (358 mg, 89% yield)[1].
| [Purification Methods]
Recrystallise it from large volumes of Me2CO. Sublime it at 200-250o/1mm instead of distilling it. [Beilstein 2 IV 1318.] | [References]
