Infobox-Referenzen Phenol, auch bekannt als Karbolsäure, ist eine aromatische organische Verbindung mit der molekularen Formel C6H5OH. Es ist ein weißer kristalliner Feststoff, der flüchtig ist. Das Molekül besteht aus einer Phenylgruppe (-C6H5), die an eine Hydroxylgruppe (-OH) gebunden ist. Es ist mild sauer, aber erfordert sorgfältige Behandlung aufgrund seiner Neigung, Verbrennungen zu verursachen.
