Okwu mmalite
Cresol, nke a maara nke ọma dị ka methylphenol (aha bekee Cresol), bụ ngwakọta organic. Ihe na-esonụ bụ mmalite nke akụrụngwa, ojiji, ụzọ nkwadebe na ozi nchekwa nke p-toluenol:
Ogo:
Ọdịdị: Cresol bụ mmiri na-enweghị agba ma ọ bụ na-acha odo odo na-esi ísì ụtọ phenolic pụrụ iche.
Solubility: Ọ na-agbaze na alcohols, ethers na ethers, na ntakịrị soluble na mmiri.
