Aromatic Intermediate & Inhibitor
Hydroquinone
A well-known antioxidant and polymerisation inhibitor — a dependable intermediate for petrochemicals, coatings and fine chemicals.
C6H6O2 · Benzene-1,4-diol
Overview
Hydroquinone is an aromatic organic compound and white granular solid synthesised from phenol. Known for its antioxidant properties, it is used mainly as a polymerisation inhibitor for monomers in the petrochemical industry — supporting process, transport and storage stabilisation. It also stabilises inks, coatings, rubbers and polymers, serves as a chemical intermediate for pharmaceuticals, chemicals and agrochemicals, and is used in photographic processing. Some uses (cosmetics, bleaching agents) are regulated or prohibited; relevant European or national regulations must be observed.
Applications
- Polymerisation inhibitor for petrochemical monomers
- Process, transport and storage stabilisation
- Stabiliser for inks, coatings, rubbers and polymers
- Intermediate for pharmaceuticals and agrochemicals
- Photographic processing (industrial & professional)
