Cresols, also known as methylphenols, are a group of organic compounds that are phenol derivatives. They have the general formula (C7H8O) and exist in three isomeric forms: ortho-cresol (2-methylphenol), meta-cresol (3-methylphenol), and para-cresol (4-methylphenol). The structural difference lies in the position of the methyl group relative to the hydroxyl group on the benzene ring.
Uses of Cresols:
1. Disinfectants and Antiseptics:
– Cresols, especially para-cresol, are used as disinfectants and antiseptics in various applications.
2. Chemical Intermediates:
