용도

4-Methoxyphenol is an active ingredient and used in dermatology. It is employed as a pharmaceutical drug in skin depigmentation. It is used as polymerization inhibitors. For example, in the radical polymerization of acryaltes and styrene monomers. It is also used as an intermediate in the preparationagrochemicals, liquid crystals. It acts as a stabilizer for the formulation of inks, toners and adhesives. It is mainly used as an additive for textile and leather industries.

참고

Moisture sensitive. Store in a cool place. Keep the container tightly closed. Incompatible with halogens and oxidizing agents.

Primary OH groups can be protected as 4-methoxyphenyl ethers by Mitsunobu alkylation. These are stable to aqueous acid or base at 1000, high pressure hydrogenation, ozonolysis, LiAlH4, or Cr(VI) reagents. Deprotection can be effected with CAN: Tetrahedron Lett., 26, 6291 (1985); 29, 1389 (1988), or anodic oxidation: Carbohydr. Res., 277, 321 (1995).
