High-purity hydroquinone for photographic developers, polymer stabilizers, antioxidants, and organic synthesis intermediates. Full COA provided with every shipment.
Hydroquinone (1,4-dihydroxybenzene, 1,4-benzenediol) is a white crystalline organic compound with strong reducing properties. It is one of the most widely used aromatic diols in the chemical industry, valued for its reactivity as a reducing agent, antioxidant, and polymerization inhibitor.
ZHAOYUAN supplies photographic-grade hydroquinone at ≥99% purity with full COA documentation. The product meets the requirements for use in photographic developers, rubber antioxidants, polymer stabilization, and chemical synthesis applications.

Hydroquinone is harmful if swallowed, inhaled, or absorbed through skin. It may cause skin sensitization and eye irritation. Handle with appropriate PPE (gloves, eye protection, respiratory protection in dusty conditions). Full MSDS available on request. Buyers are responsible for compliance with local import and handling regulations.
Hydroquinone is used as a reducing agent in black-and-white photographic developers, a polymerization inhibitor for acrylic and methacrylic acid monomers, a raw material for rubber and plastic antioxidants, a chemical intermediate for pharmaceuticals and dyes, and — under regulated concentration limits — an active ingredient in skin-lightening cosmetic formulations.
ZHAOYUAN supplies photographic-grade hydroquinone at ≥99% purity, with melting point 171–175°C and tight limits on iron (≤0.002%) and lead (≤0.002%) content. A full certificate of analysis (COA) is provided with every shipment.
Hydroquinone prevents premature polymerization during the production and storage of vinyl monomers such as acrylic acid and methacrylic acid, protecting these reactive intermediates from degrading before their intended use.
Yes — hydroquinone is harmful if swallowed, inhaled, or absorbed through skin, and may cause skin sensitization and eye irritation. Appropriate PPE (gloves, eye protection, and respiratory protection in dusty conditions) is required, and full MSDS documentation is available on request.
Store in a cool, dry, well-ventilated area away from light, heat, and oxidizing agents, with containers kept tightly sealed. Shelf life is 1 year from the manufacture date under recommended storage conditions.
