4-Methoxyphenol CAS 150-76-5
4-Methoxyphenol CAS 150-76-5 in the form of white flake or waxy crystal, it is mainly used in vinyl-based plastic monomer polymerization inhibitor, UV inhibitor, dye intermediate and used in the synthesis of edible oils and cosmetics antioxidant BHA. The biggest advantage of 4-Methoxyphenol is that the monomer added with MEHQ does not need to be removed when it is copolymerized with other monomers. It can be directly copolymerized with three elements, and can also be used as antioxidant and antioxidant.

4-Methoxyphenol (MEHQ) CAS 150-76-5 is widely used as a polymerization inhibitor and stabilizer in acrylic acid, methacrylic acid, acrylate esters, and vinyl monomer systems. It effectively prevents premature polymerization during storage and transportation.
Main applications include:
- Acrylic acid and acrylate monomer stabilization
- UV coatings, inks, and adhesive systems
- Unsaturated polyester resin production
- Cosmetic antioxidants and BHA synthesis
- Dye intermediates and pharmaceutical intermediates
- Formulations used with UV curing monomers and polymerization inhibitor products
4-Methoxyphenol is commonly used in monomer systems such as “4-Acryloylmorpholine”to improve storage stability and transportation safety.
- Excellent polymerization inhibition efficiency
- Improves storage stability of acrylic monomers
- Good compatibility with acrylate and vinyl systems
- Effective at low dosage levels
- Widely used in coatings, adhesives, and resin industries
- Stable chemical properties and reliable industrial performance
- Important component in advanced polymer additive solutions
As a professional UV additives manufacturer, Unisunchem supplies stable-quality MEHQ and polymer stabilization solutions for global industrial customers.
