Organic peroxides yog cov organic compound uas muaj peroxide functional pawg (ROOR '). Yog tias R' yog hydrogen, cov tshuaj no hu ua hydroperoxides, uas tau tham hauv kab lus no. Peresters yog peroxy analogs ntawm esters thiab muaj cov qauv dav dav RC (O) OOR. OO daim ntawv cog lus ntawm peroxides tau yooj yim tawg, tsim cov dawb radicals hauv daim ntawv RO • (dots sawv cev rau cov khoom siv hluav taws xob tsis sib xws). Yog li ntawd, Organic peroxides tuaj yeem siv los ua ib qho kev pib rau qee hom polymerization, xws li epoxy resin siv hauv iav reinforced plastics. MEKP thiab Benzoyl peroxide feem ntau yog siv rau lub hom phiaj no. Txawm li cas los xij, tib lub zog kuj txhais tau hais tias Organic peroxides tuaj yeem txhob txwm los yog tsis txhob txwm ua kom tawg polymerization hauv cov ntaub ntawv uas tsis muaj tshuaj lom neeg, cov txheej txheem uas tau siv rau hauv cov khoom tawg. Organic peroxides,
OO daim ntawv cog lus ntev hauv peroxides yog li 1.45 Å, thiab lub kaum sab xis ROO (R=}H, C) yog li 110 degree (dej zoo li). Feem ntau, C − O − O − R (R=H, C) Dihedral lub kaum sab xis yog li 120 degree. Daim ntawv cog lus OO yog qhov tsis muaj zog, nrog lub zog sib txuas ntawm 45-50 kcal / mol ({11}} kJ / mol), uas tsawg dua ib nrab ntawm lub zog ntawm CC, CH, thiab CO daim ntawv cog lus.
Peroxides ua lub luag haujlwm tseem ceeb hauv biology. Ntau yam ntawm biodegradation lossis kev laus yog vim qhov tsim thiab lwj ntawm peroxides tsim los ntawm oxygen hauv huab cua. Ntau yam ntawm cov tshuaj lom neeg lom neeg thiab khoom siv tshuaj tua kab mob yog siv los tawm tsam cov teebmeem no. Muaj ntau pua tus paub txog peroxides thiab hydroperoxides tau los ntawm fatty acids, steroids, thiab terpenes. Fatty acids tsim ntau 1,2-dioxenes. Lub biosynthesis ntawm prostaglandins yog ua los ntawm endoperoxides (ib chav kawm ntawm bicyclic peroxides). Hauv fireflies, Luciferase catalyzes oxidation ntawm Luciferin los tsim peroxy compound 1,2-di Oxetane. Dineneneba oxheterocyclobutane tsis ruaj khov thiab yuav ploj mus sai sai rau hauv cov pa roj carbon dioxide thiab zoo siab ketones, uas tso tawm ntau lub zog los ntawm luminescence (Bioluminescence).
