Para-cresol, also known as 4-methylphenol, is a chemical compound belonging to the class of organic compounds known as phenols. It is structurally similar to other phenols but contains a methyl group attached to the benzene ring at the para position, hence the name para-cresol.

Here are some key points about para-cresol:

1. Chemical Structure: Para-cresol has the chemical formula C7H8O and is composed of a benzene ring with a hydroxyl group (-OH) and a methyl group (-CH3) attached to it. The methyl group is located at the para position, which means it is directly opposite to the hydroxyl group.

2. Physical Properties: Para-cresol is a colorless to pale yellow liquid with a strong, pungent odor. It is soluble in organic solvents like ethanol and ether but has limited solubility in water.

3. Occurrence: Para-cresol occurs naturally in coal tar, crude oil, and wood tar. It is also found as a component of creosote, a mixture of organic compounds used as a wood preservative and antiseptic.

4. Uses:

   • Antiseptic: Para-cresol has antiseptic properties and has been used in the past as a topical antiseptic for treating wounds and skin infections.
   • Disinfectant: It is used in the formulation of disinfectants and sanitizers for various applications, including industrial and household use.
   • Chemical Intermediates: Para-cresol is employed in the synthesis of other chemicals, including antioxidants, fragrances, and pharmaceuticals.
   • Polymerization Catalyst: It serves as a catalyst in certain polymerization reactions, particularly in the production of resins and plastics.

5. Health and Safety: Para-cresol can be irritating to the skin, eyes, and respiratory tract upon exposure. Prolonged or repeated exposure to high concentrations may cause adverse health effects. Proper handling, ventilation, and personal protective equipment are necessary when working with para-cresol or products containing it.
