Pharmaceutical Hydroquinone with CAS No. 123-31-9 Product Overview Hydroquinone is an organic compound in which two para hydrogens of benzene are replaced by hydroxyl groups. White crystals. Also called hydroquinone. Poisonous, adults mistaken for 1 gram, you can have headaches, dizziness, tinnitus, pale and other symptoms. Hydroquinone encounters fire, heat and flammability, reacts with strong oxidants, and releases carbon monoxide by high heat. Hydroquinone is mainly used in the preparation of black and white developer, anthraquinone dyes, azo dyes, rubber antioxidants, stabilizers and antioxidants.Hydroquinone is flammable and easily exposed to light in the air. Its aqueous solution can be oxidized to brown in air and oxidized faster in alkaline media. Soluble in ether and ethanol, slightly soluble in benzene. It is reducible, and the brown benzoquinone (C6H4O2) is obtained through mild oxidation. The benzoquinone is reduced to obtain hydroquinone. P-benzoquinone-hydroquinone redox pairs exist in many biomolecules, such as coenzyme Q and so on.The phenolic hydroxyl of hydroquinone is weakly acidic and can lose one or two protons to generate the corresponding phenolate anion. It is mainly used as reducing agent, developer (reduction of silver halide to silver), polymerization inhibitor of monomer (acrylic acid, methyl methacrylate), and skin whitening agent. Hydroquinone ether is a raw material for the production of dyes and perfumes.
