4-METHOXYPHENOL CAS 150-76-5 is an important intermediate for fine chemical products such as pharmaceuticals, spices, and pesticides. It can also be used as a polymerization inhibitor, antioxidant, plasticizer, etc., with a very wide range of applications. It is mainly used as a polymerization inhibitor for producing alkene monomers such as acrylonitrile, acrylic acid and its esters, methacrylic acid and its esters. Its greatest advantage is that when in use, it is not necessary to remove p-hydroxyanisole; it can directly participate in polymerization. It is also used in the synthesis of antioxidants, plasticizers, and food additives (BHA), etc. Efficient Antioxidant and Polymerization Inhibiting Performance: It rapidly scavenges free radicals, effectively inhibiting the oxidative deterioration and self-polymerization of polymers (such as rubber, plastics, resins) and monomers (such as styrene, acrylates) during storage, transportation, and processing. Its polymerization inhibition efficiency is superior to that of similar phenolic antioxidants. Excellent Thermal Stability and Compatibility: It is resistant to high temperatures, does not decompose or volatilize under conventional processing temperatures (e.g., plastic extrusion, rubber vulcanization), and has good compatibility with most polymers, organic solvents, and other additives (e.g., plasticizers, stabilizers) without affecting the appearance and performance of the final products. Low Toxicity and High Safety: It has low acute toxicity, with weak oral and dermal toxicity. It meets the safety standards for food contact materials, cosmetics, and other fields, and is relatively friendly to humans and the environment. Wide Applicability and Controllable Cost: It has moderate water and oil solubility, suitable for both aqueous and oil-based systems. Meanwhile, its mature production process keeps the price lower than high-end special antioxidants, offering excellent cost-effectiveness.
