      Product Detail  


    Methylhydroquinone, identified by CAS 95-71-6 and often referred to as Toluhydroquinone (THQ), is a specialized organic compound valued for its powerful antioxidant and inhibitory properties.

    Appearing as a white to light beige crystalline powder with the chemical formula C7H8O2, it is a derivative of hydroquinone with a methyl group in the ortho position. This structural feature enhances its effectiveness as a polymerization inhibitor for vinyl monomers and unsaturated resins. Beyond its role in the polymer industry, THQ is a critical component in photographic developers and a versatile intermediate in the synthesis of high-end fine chemicals, dyes, and pharmaceutical precursors.


    Applications

    Polymerization Inhibition The industry standard for stabilizing vinyl acetate, acrylic acid monomers, and unsaturated polyester resins during storage and shipping.

    Antioxidant and Stabilizer Used to protect fatty esters, linseed oil, and other industrial oils from oxidative rancidity and degradation.

    Photographic Chemicals Acts as a high-performance developing agent in black-and-white photographic processes, facilitating clear image formation.

    Chemical Intermediates A vital building block for the synthesis of complex dyes, agricultural chemicals, and pharmaceutical active ingredients (APIs).
