• 説明

  Retinyl acetate (retinol acetate, vitamin A acetate,127-47-9) 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.

• 化学的特性

  Retinyl acetate is a yellow, prism-shaped crystal and a lipid-soluble compound, with better chemical stability than vitamin A. In clinical practice, either vitamin A acetate or its palmitate form is typically dissolved in vegetable oil for administration, where it is hydrolyzed by enzymes in the body to release active vitamin A. The form of vitamin A listed in the Chinese Pharmacopoeia refers to the active vitamin A compound.

• 使用

  Retinyl acetate has been used:
  
  • a control diet to study its effect at different developmental periods in fish larvae
  • to study its inhibitory effects on Mycobacterium avium?subspecies?paratuberculosis?(MAP) strains
  • as an internal standard in high performance liquid chromatography (HPLC) to quantify vitamin A in fortified milk
  
  

• 製造方法

  A method for preparing retinyl acetate the following steps:
  Under alkaline conditions, 3-methyl-4-oxo-2-butene-1-yl acetate (referred to as C5 aldehyde ester) and tetraethyl methylene diphosphate undergo a condensation reaction to form an intermediate C6 phosphate (chemical name: 5-(diethyl phosphate)-3-methyl-2,4-hexadiene-1-acetate).
  Under alkaline conditions, the C6 phosphate undergoes a transposition reaction. C14 aldehyde (chemical name: 2-methyl-4-(2,6,6-trimethyl-1-cyclohexene-1-yl)-3-butene-1-aldehyde) is then added to undergo a Wittig-Horner condensation reaction, yielding retinyl acetate.

• 一般的な説明

  Retinyl acetate is suitable for use in the retention identification of the analyte when using HPLC and GC. Not intended for use as an activity reference standard. It has been thoroughly evaluated to ensure the utmost quality. Neat, unless otherwise noted. Certificate of Composition provided with the purchase.

• 安全性プロファイル

  Moderately toxic by ingestion. Experimental teratogenic and reproductive effects. Questionable carcinogen with experimental neoplastigenic data. Mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes. See also VITAMIN A.

• 純化方法

  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.]
