Cetonas
As cetonas são compostos orgânicos caracterizados pela presença de um grupo carbonilo (C=O) ligado a dois átomos de carbono. Esses compostos são altamente versáteis e desempenham um papel crucial em várias reações químicas, incluindo oxidação, redução e condensação. As cetonas são intermediários essenciais na síntese de produtos farmacêuticos, fragrâncias e polímeros. Na CymitQuimica, oferecemos uma ampla gama de cetonas de alta qualidade para apoiar suas aplicações de pesquisa e industriais.

CAS:<p>1,3-Indanedione is a precursor of indane diones that is used in the synthesis of fluorescent molecules. In the presence of light, 1,3-indanedione produces light emission and can be used as a chemiluminescent probe. In the presence of trifluoroacetic acid and copper complex, 1,3-indanedione undergoes intramolecular hydrogen transfer to form an intermediate which reacts with malonic acid to form an alkyl radical. The alkyl radical then reacts with hydrochloric acid to produce an ionic polymerization product. The biological sample is reactive with fatty acids and can be used for the detection of prostate cancer cells.</p>Fórmula:C9H6O2Pureza:(%) Min. 70%Cor e Forma:PowderPeso molecular:146.14 g/molMeOSuc-Ala-Ala-Pro-Ala-chloromethylketone
CAS:<p>MeOSuc-Ala-Ala-Pro-Ala-chloromethylketone is a peptidyl substrate for the enzyme carboxypeptidase A.
