产品说明

一般描述

Cholecalciferol, also called vitamin D3, promotes the absorption of calcium and phosphorus in the body to regulate bone growth. It is most commonly found in humans and animals and is produced in our skin when exposed to sunlight. It is used to treat and prevent bone disorders (such as rickets, osteomalacia).

应用

Cholecalciferol has been used as an internal standard in high-performance liquid chromatography (HPLC) to analyze serum vitamin D levels. It has also been used as a standard in liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS) to quantify vitamin D3 in sunflower oil.
Cholecalciferol may be used as an analytical reference standard for the determination of the analyte in pharmaceutical formulations by liquid chromatography.
