High-purity monomers, functional excipients, and specialty fine chemicals engineered for global industrial and cosmetic applications.
Comprehensive chemical identification, physical-chemical properties, quality standards, and analytical benchmarks for industrial buyers.
Methylhydroquinone (CAS Number: 95-71-6), also commonly designated as 2-Methyl-1,4-benzenediol, Toluhydroquinone (THQ), or 2-Methylhydroquinone, is a critical substituted hydroquinone organic compound. Operating as a ultra-high efficiency polymerization inhibitor, free radical scavenger, and chemical intermediate, CAS 95-71-6 plays an irreplaceable role in stabilizing unsaturated monomers, refining specialty resins, and serving as a core building block for pharmaceuticals and agrochemicals.
When sourcing CAS 95-71-6 from primary chemical manufacturers and OEM factories, global procurement officers must evaluate purity thresholds, residual isomer ratios, heavy metal traces, and moisture control. JIMPOCHEM delivers industrial-grade and pharmaceutical-grade Methylhydroquinone with consistent purity assays exceeding 99.5% by HPLC.

Strategic market intelligence for chemical supply chain executives, detailing macro consumption patterns, growth drivers, and regional sourcing transitions.
As global acrylic acid, methacrylates, and styrene production scales to meet packaging and automotive needs, CAS 95-71-6 has emerged as a preferred thermal radical inhibitor during storage and transcontinental maritime transit.
International buyers from North America and Europe are increasingly securing long-term strategic contracts with certified Chinese manufacturers like JIMPOCHEM to hedge against Western inflation and energy-cost vulnerabilities.
Methylhydroquinone serves as an essential precursor for next-generation fungicides, pest-management agents, and active pharmaceutical intermediates (APIs), driving high-volume baseline growth annually.
Tailored chemical engineering solutions for downstream manufacturing sectors requiring precise stabilization and chemical transformation.
In the production and bulk transportation of acrylic acid, methyl methacrylate (MMA), acrylonitrile, and unsaturated polyester resins (UPR), premature free-radical polymerization poses severe safety risks and operational downtime.
The Solution: CAS 95-71-6 acts as a highly efficient radical capturer at low concentrations (typically 10 to 200 ppm). Compared to standard hydroquinone (HQ), Methylhydroquinone exhibits superior solubility in organic monomer matrices and enhanced thermal resistance during vacuum distillation.
Elastomeric compounds and synthetic rubbers (such as butadiene and chloroprene rubbers) undergo thermal-oxidative degradation when exposed to atmospheric oxygen and elevated processing temperatures.
The Solution: Incorporating industrial-grade Methylhydroquinone prevents chain scission and cross-linking reactions. It protects mechanical flexibility and extends the operational lifespan of rubber seals, tires, and industrial gaskets under severe operating environments.
Formulating modern crop protection agents requires reactive, clean chemical intermediates that minimize unwanted side-product pathways during electrophilic aromatic substitution reactions.
The Solution: JIMPOCHEM supplies CAS 95-71-6 with ultra-low trace iron (≤10 ppm) and minimal insoluble matter, ensuring high stoichiometric yields in the synthesis of heterocyclic compounds, dyes, and crop protective intermediates.
In UV-curable inks, coatings, and 3D printing resins, storage stability is paramount to prevent premature gelation in the container prior to UV irradiation exposure.
The Solution: CAS 95-71-6 provides an optimal balance: robust dark-storage stabilization without hindering photo-initiator efficiency once high-intensity UV curing lamps are activated during application.
