4-Methoxyphenol (MEHQ) (CAS: 150-76-5) is mainly used as polymerization inhibitor, ultraviolet inhibitor, dye intermediate and antioxidant BHA for synthesis of edible oils and cosmetics. Its biggest advantage is that the monomer after adding MEHQ and other monomers do not need to be removed when copolymerizing, it can be directly copolymerized by ternary, and it can also be used as an antioxidant, antioxidant, etc.
4-Methoxyphenol is an important intermediate for fine chemical products such as medicine, perfume, pesticide, liquid crystals, etc. It is also used for the synthesis of antioxidant, plasticizer and food additive (BHA). It can also be used as polymer inhibitor, antioxidant, plasticizer, etc., with a wide range of uses.
Poison by intraperitoneal route. A skin irritant. When heated to decomposition it emits acrid smoke and fumes. See also ETHERS.
