Hlor monoksid ili klor monoksid je kemijski radikal sa formulom ClO. Igra važnu ulogu u procesu oštećenja ozonskog omotača. U stratosferi, atomi klora reagiraju sa molekulama ozona kako bi stvorili klor-monoksid i kisik.

Cl· + O₃ → ClO· + O₂

Ova reakcija izaziva oštećenje ozonskog omnotača.^[4] Ova reakcija se može nastaviti i ClO· radikali mogu nastaviti reagirati ovako:

ClO· + O· → Cl· + O₂

regenerirajući klor radikal. Tako se opća reakcija za raspad ozona katalitira preko klora, jer klor na kraju ostaje nepromijenjen. Opća reakcija je:

O· + O₃ → + 2O₂

Ovo je predstavaljalo značajan učinak korištenja CFC-a na gornju stratosferu. Nereaktivna priropda CFC-a dozvoljava da proe u strastforeu gdje prolazi kroz foto-disocijaciju gdje se stvaraju Cl radikali. Oni potom stvaraju klor monoksid, i ovaj ciklu se može nastaviti dok radikali reagiraju i stvore diklor dioksid, završavajući radikalsku reakciju. S obzirom da je koncentracija CFC-a u atmosferi vrlo niska, vjerojatnost završavanja reakcije je vrlo niska, što znači da se svaki radikal može razbiti nekoliko tisuća molekula ozona.
