How do i Dissolve my Vitamin A acetate ?

02 July 2020 1 2K Report

I want to do quantitative analysis for vitamin A acetate raw material using HPLC method, but my sample cannot dissolve in many organic solvent such as methanol,ethanol,chloroform and hexane.

is there any recommended solvent that i can use for dissolve it ?

Carlos Joel Salas-Montantes

Some raw material fo vitamins can not dissolve directly like other APIs because these are added some other components for stability. You need to investigate how this raw material is and in base on that create a method for a selective extraction of the vitamin. Good luck
