p-Benzoquinone CAS 106-51-4 - High-Quality China Suppliers and Factory for Organic Synthesis

,

● Molecular Formula: C6H4O2

,
Physical and Chemical Properties:
,

P-Benzoquinone is a yellow crystalline compound with a robust benzene ring structure and notable oxidizing properties. It effectively displaces iodine from iodide in acidic solutions, while also reducing itself to hydroquinone, a valuable reducing agent in organic synthesis. As a key raw material in the chemical industry, p-benzoquinone must be handled with care, as its vapor can irritate the cornea and mucous membranes. Prolonged exposure to high concentrations of p-benzoquinone vapor poses a risk of eye damage. China is a leading manufacturer and supplier of p-benzoquinone, providing high-quality products from its extensive factory facilities.
