Product Description
Hydroquinone (HQ), CAS No. 123-31-9, is a vital organic compound of the phenol family, renowned for its exceptional reducing and antioxidant properties. It stands as an indispensable basic raw material in the modern chemical industry. The two para-hydroxyl groups in its molecular structure impart unique chemical reactivity, enabling it to play a crucial role in a wide array of applications.
As a highly effective free-radical scavenger, Hydroquinone is the preferred polymerization inhibitor for unsaturated monomers such as acrylic acid, methyl methacrylate (MMA), and styrene during their production, storage, and transportation. Additionally, it serves as a classic developer for black-and-white photography, an antioxidant in the rubber and food industries, and a core intermediate for synthesizing various dyes, pharmaceuticals, and agrochemicals. We are dedicated to providing high-purity, superior-quality industrial and photographic grade Hydroquinone to meet your diverse application needs.
