p-Benzoquinone CAS 106-51-4 - China Suppliers & Factory for High-Quality Organic Synthesis Raw Materials

,

● Molecular Formula: C6H4O2

,
Physical and Chemical Properties:
,

P-Benzoquinone is a yellow crystalline compound known for its strong oxidizing properties. It is characterized by its structural relationship to the benzene ring and the ability to displace iodine from iodide in acidic solutions. This compound plays a crucial role in the organic synthesis industry, with its reduction product, hydroquinone, functioning as a reducing agent. Caution is advised as the vapor of p-benzoquinone can irritate the eyes and mucous membranes; prolonged exposure to high concentrations may lead to serious eye damage. As a leading supplier and factory based in China, we ensure the highest quality of p-benzoquinone for all your industrial applications.
