CAS 120-80-9: Catechol

Description:Catechol, also known as 1,2-dihydroxybenzene, is an aromatic organic compound characterized by the presence of two hydroxyl (-OH) groups attached to a benzene ring. It is a colorless to light brown solid at room temperature and has a distinctive sweet, aromatic odor. Catechol is soluble in water, alcohol, and ether, which enhances its utility in various chemical applications. It is commonly used as a precursor in the synthesis of various chemicals, including pharmaceuticals, agrochemicals, and dyes. Additionally, catechol serves as a reducing agent and is involved in the production of certain polymers and resins. Its reactivity is attributed to the hydroxyl groups, which can participate in various chemical reactions, such as oxidation and substitution. Catechol is also known for its role in biological systems, particularly in the metabolism of certain compounds. However, it is important to handle catechol with care, as it can be toxic and irritating to the skin and eyes. Proper safety precautions should be observed when working with this compound.
