Vitamin D3 octanoate, an ester derived from vitamin D3, is commonly known as cholecalciferol. Cholecalciferol is a naturally occurring form of vitamin D with notable properties such as inducing cell differentiation and impeding cancer cell proliferation.
23,25-Dihydroxy-24-oxovitamin D3, a prominent metabolite of 24(R),25-Dihydroxyvitamin D3, holds significant potential for studying metabolic disorders[1].
Impurity B of Calcitriol is an impurity of Calcitriol. Calcitriol is the hormonally active form of vitamin D, Calcitriol is the active metabolite of vitamin D3 that activates the vitamin D receptor (VDR).
