Specification

Vitamin D2 is a provitamin form of vitamin D, also called Ergocalciferol. With then CAS number 50-14-6, Ergocalciferol may be used as a vitamin D supplement, and a 2011 clinical guideline considered it to be as effective as cholecalciferol. Ergosterol gliadin in ethanol, in the UV irradiation open-loop, the reaction solution vacuum concentration, frozen, filtration. Filter liquid nitrogen, vacuum concentration to dry, vitamin D2 crude oil, refined products in. Vitamin D2 is also called VIOSTEROL;(3beta,5Z,7E,22E)-9,10-Secoerga-5,7,10(19),22-tetraen-3-ol; (3beta,5Z,7E,22E)-9,10-Secoergosta-5,7,10(19)-,22-tetraen-3-ol; (3-beta,5z,7e,22e)-9,10-secoergosta-5,7,10,(19),22-tetraen-3-ol; (5E,7E,22E)-9,10-Secoergosta-5,7,10,22-tetraen-3-ol.
