[Description]

Retinyl acetate (retinol acetate, vitamin A acetate) is a natural form of vitamin A. It is the acetate ester of retinol. It consists of yellow crystals which are greasy or sticky. It has a mild, characteristic odor. It has potential antineoplastic and chemo-preventive activities. It can be used to fortify food with vitamin A. As vitamin A acetate can induce cell differentiation and inhibit cell proliferation, it is used in skin-conditioning agent.

[Purification Methods]

The acetate is separated from retinol by column chromatography, then crystallised from MeOH. [Kofler and Rubin Vitamins and Hormones (NY) 18 315 1960 for purification methods]. Store it in the dark, under N2 or Ar, at 0o. [Beilstein 6 IV 4135.]
