META CRESOL (108-39-4)

Product Overview

Meta-Cresol, also 3-methylphenol, is an organic compound with the formula CH₃C₆H₄. Meta Cresol is a colorless liquid with a distinct dry, tarry, medicinal–leathery odor. Often found alongside p-cresol, it poses challenges in separation.

Utilized as a disinfectant and solvent, m-Cresol finds applications in degreasing compounds, paintbrush cleaners, and additives in lubricating oils. It was formerly used for disinfecting poultry houses but discontinued due to adverse effects.

Considered a questionable carcinogen, m-Cresol can cause mucosal irritation, skin burns, and severe eye damage. It is sensitive to air, heat, and light and reacts vigorously with certain substances. Classified as a poisonous and corrosive material, m-Cresol is shipped under hazardous labels to indicate its risks.
