Cresol, wanda aka fi sani da methylphenol (sunan Ingilishi Cresol), wani fili ne na kwayoyin halitta. Mai zuwa shine gabatarwa ga kaddarorin, amfani, hanyoyin shiri da bayanan aminci na p-toluenol:

inganci:

Bayyanar: Cresol ruwa ne mara launi ko rawaya tare da ƙamshi na musamman na phenolic.

Solubility: Yana da narkewa a cikin alcohols, ethers da ethers, kuma dan kadan mai narkewa cikin ruwa.

Abubuwan sinadarai: Cresol wani abu ne na acidic wanda ke amsawa tare da alkali don samar da gishiri daidai.

Amfani:

Amfanin masana'antu: Ana amfani da Cresol azaman abin adanawa, maganin kashe kwayoyin cuta, da sauran ƙarfi a cikin kera abubuwan kiyayewa. Hakanan yana aiki azaman mai kara kuzari da ƙarfi a cikin masana'antar roba da guduro.

Amfanin noma: Ana iya amfani da Toluene a fannin aikin gona azaman maganin kwari da fungicides.
