Methylhydroquinone

Methylhydroquinone (CAS 95-71-6), also known as 2,5-Dihydroxytoluene, is a substituted hydroquinone derivative used across polymer, cosmetic, and flavor industries as an antioxidant and UV stabilizer.

Its ability to scavenge free radicals makes it a functional additive in systems where oxidative degradation or premature cure must be controlled during the manufacturing process.

In plastics and polymer manufacturing, it acts as a polymerization inhibitor, preventing premature crosslinking during storage and processing of reactive monomers and resins.

Cosmetic formulators incorporate it into topical preparations where antioxidant stabilization of the formulation matrix is required to maintain product integrity and shelf life.

In flavor and fragrance applications, it contributes to aroma profiles and functions as a preservative component in finished flavor systems for various consumer goods.

Pharmaceutical manufacturers also use it as a synthetic intermediate in the production of active ingredients and specialty fine chemicals for the global healthcare market.

The product is supplied as a white to off-white crystalline powder and is available in technical and pharmaceutical-intermediate grades with purity levels typically at 98% or higher.

Packaging options range from kilogram-scale bags to bulk drum quantities to suit both R&D and commercial production requirements for industrial and laboratory applications.
