Ergocalciferol or Calciferol or Vitamin D2
CAS Number: 50-14-6
Molecular Formula: C28H44O
Molecular Weight: 396.66
Ergocalciferol or Calciferol or Vitamin D2
Ergocalciferol or Vitamin D2 or Calciferol, is a type of vitamin D found in food and used as a dietary supplement. It works by helping the body to use more of the calcium found in foods or supplements.

Vitamin D2
Ergocalciferol; Vitamin D
C28H44O --- Formula weight 396.66
CAS 50-14-6
DESCRIPTION
Vitamin D2 occurs as white crystals. It is affected by air and by light. It is insoluble in water, but it is soluble in alcohol, in chloroform, in ether, and in fatty oils.
Function: Nutrient.
REQUIREMENTS
Identification:
A. To pass the chromatographic test.
B. The infrared absorption spectrum of a potassium bromide dispersion of the sample, in the range of 2 to 12 µm, exhibits maxima only at the same wavelengths as those of a similar preparation of USP Ergocalciferol Reference Standard.
C. The ultraviolet absorption spectrum of the sample in alcohol solution exhibits inflections at the same wavelengths as that of USP Ergocalciferol Reference Standard, similarly measured, and the respective absorptivities at 265 nm do not differ by more than 3.0%.
Assay: Not less than 97.0% and not more than 103.0% of C28H44O.
Ergosterol: Passes test.
Melting Range: Between 115° and 119°.
Optical (Specific) Rotation [α]D25°: Between +103° and +106°.
Reducing Substances: Passes test.
Ergocalciferol is also offered as per BP Ph Eur grade monograph.
