Pyridinium Dichromate (PDC) ama Pyridinium Chlorochromate (PCC) ee ku jira warbaahinta anhydrous sida dichloromethane oxidizes aalkolada aasaasiga ah si aldehyde iyada oo iska ilaalinaya xad-dhaaf ah acids karbosilic.PCC waxay ahayd markii ugu horaysay oksidant-door cusub oo uu helay EJ Corey 1975 ka dib markii uu sameeyay cilmi baaris.Waa reagent ee isku-dhafka dabiiciga ah ee loo isticmaalo ugu horrayn oksaydhka alkolada si loo sameeyo carbonyls.Iskudhisyo kala duwan oo la xidhiidha ayaa lagu yaqaan falcelin isku mid ah.PCC waxay siisaa faa'iidada oksaydhka alkolada ee aldehyde ama ketones, halka qaar badan oo kale oo reagen ah ay yihiin kuwo aan la dooran.Pyridinium Chlorochromate waxaa loo isticmaalaa sidii wakiilka oksaydhiyaha si loogu beddelo aalkolada aasaasiga ah iyo kuwa sare ee aldehyde iyo ketones siday u kala horreeyaan.Waxay ku lug leedahay diyaarinta cyclohexanone, (-) -pulegone iyo lactones.Waxay ka ciyaartaa door muhiim ah mono-oxidation ee xylenes ilaa tolualdehydes iyo arylhydroxyamines ilaa xeryahooda nitroso.Intaa waxaa dheer, waxaa loo isticmaalaa sidii oksaydhiyeyaasha amino acids, L-cystine, aniline, cycloalkanols, vicinal iyo non-vicinal diols iyo sidoo kale falcelinta oksaydhka Babler.
