• p-Methoxy Phenol (PMP)
  • 4-Hydroxy Anisole
  • Hydroquinone Mono Methyl Ether (HQMME)
Molecular Formula

MEHQ is used as a Polymerization inhibitor in the manufacturing of Acrylics, Methacrylic, other Acrylates, Vinyl Acetate Monomer (VAM), Styrene Monomer and in Unsaturated Polyesters etc.

We are the only Chemical Enterprise in the World which has been successful in commercializing hydroxylation of Anisole to produce MEHQ. The process is unique, novel and environment-friendly producing only water as the by-product. We have four independent production lines to produce MEHQ.

We are fully registered with REACH.
