Chemische Eigenschaften

Ergocalciferol is an odorless white crystalline solid


The synthetic form of vitamin D. Prepared from ergosterol by UV irradiation in a suitable solvent. Commercial solutions are usually made with propylene glycol or sesame oil. Antirachitic


antirachitic vitamin; LD50 (rat) 56 mg/kg po




Vitamin d2 is fat-soluble, and is stable unless oxidized. It is necessary for growth and maintenance of teeth and bones and the normal utilization of calcium and phosphorus; it is used medicinally in the treatment of rickets and as a dietary supplement. Its sources include fish liver and vitamin d-fortified milk.


Vitamin D2 is formed by photochemical cleavage of ergosterin, which is a side-product of many fermentation processes. Microorganisms usually contain up to 3 percent of ergosterin.


ChEBI: A vitamin D supplement and has been isolated from alfalfa.


Deltalin (Lilly); Drisdol(Sanofi Aventis).

Allgemeine Beschreibung

Odorless white crystals. Used as a dietary supplement and food additive.

Reaktivität anzeigen

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.

Health Hazard

Vitamin D2 poisoning disturbs calcium metabolism and causes kidney damage. Vitamin D2 in a single acute ingestion presents no toxic hazards. Daily ingestion in excess of 5000 units/day in children or 7500 units/day in adults will produce toxic symptoms associated with hypervitaminosis D. Those with hypercalcemia are at a greater risk.


Shows signs of decomposition when stored for a few days at room temperature.


Poison by ingestion, intraperitoneal, intravenous, and intramuscular routes. An experimental teratogen. Human systemic effects by ingestion: anorexia, nausea or vomiting, and weight loss. Experimental reproductive effects. When heated to decomposition it emits acrid smoke and irritating fumes.

mögliche Exposition

Used as a nutrient and/or dietary supplement food additive


Ergocalciferol (vitamin D2) is a product made by the UV irradiation of yeast ergosterol. It is a common form of vitamin D and it has very similar biological activity to that of cholecalciferol (vitamin D3) in the treatment of the vitamin D deficiency diseases (e.g. rickets). The bioactive form of this vitamin is also the 1,25-dihydroxy-derivative and this has equal antirachitic activity to that of the cholecalciferol analogue (Jones et al., 1975).


UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN3249 Medicine, solid, toxic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials

läuterung methode

It is converted into its 3,5-dinitrobenzoyl ester and crystallised repeatedly from acetone. The ester is then saponified and the free vitamin is isolated. [Laughland & Phillips Anal Chem 28 817 1956, Beilstein 6 IV 4404.]


It is unstable in light and air and in acidic media. It is inactivated within a few days under normal exposure conditions. This is due to oxidation and fragmentation of the triene functionality. Ergocalciferol is slightly more unstable, probably because of the additional alkene group in the side chain. One of the several degradation products of ergocalciferol has been identified as the ketone (8, shown in Scheme 1) formed by the loss of the methano-cyclohexanol function (Stewart et al., 1984).


Dust may be combustible and may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides.

Waste disposal

Dispose of contents and container to an approved waste disposal plant. All federal, state, and local environmental regulations must be observed. It is inappropriate and possibly dangerous to the environment to dispose of expired or waste drugs and pharmaceuticals by flushing them down the toilet or discarding them to the trash. Household quantities of expired or waste pharmaceuticals may be mixed with wet cat litter or coffeegrounds, double-bagged in plastic, discard in trash. Larger quantities shall carefully take into consideration applicable DEA, EPA, and FDA regulations. If possible return the pharmaceutical to the manufacturer for proper disposal being careful to properly label and securely package the material. Alternatively, the waste pharmaceutical shall be labeled, securely packaged and transported by a state licensed medical waste contractor to dispose by burial in a licensed hazardous or toxic waste landfill or incinerator.
