Cétones
Les cétones sont des composés organiques caractérisés par la présence d'un groupe carbonyle (C=O) lié à deux atomes de carbone. Ces composés sont très polyvalents et jouent un rôle crucial dans diverses réactions chimiques, notamment l'oxydation, la réduction et la condensation. Les cétones sont des intermédiaires essentiels dans la synthèse de produits pharmaceutiques, de parfums et de polymères. Chez CymitQuimica, nous proposons une large gamme de cétones de haute qualité pour soutenir vos applications de recherche et industrielles.

CAS :<p>1-(4-Chlorophenoxy)-1-(1H-imidazol-1-yl)-3,3-dimethyl-2-butanone (CID) is a hydroxylated fatty acid that is used as an antimicrobial agent. CID has been shown to be effective against Gram negative bacteria such as Escherichia coli and Pseudomonas aeruginosa, but not against Gram positive bacteria such as Staphylococcus aureus. The optimum concentration of CID for the inhibition of bacterial growth was determined by analyzing different concentrations of the compound in vitro. A model system was developed to investigate the effect of matrix components on the solubility of CID. LCMS/MS analysis was performed to measure the concentration of CID in wastewater samples. Climbazole, glycol ethers, and experimental solubility data were also collected and analyzed for this study</p>Formule :C15H17ClN2O2Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :292.76 g/mol3-Amino-2,3-dihydro-1λ6-thiophene-1,1-dione hydrochloride

CAS :Produit contrôlé7a,12a-Dihydroxylcholest-4-en-3-one is a structural analog of 7α,12α-dihydroxycholesterol. It has been studied for its catalytic mechanism and cavity. It is formed from the reaction of glutamate with cholesterol in a homogenate. The enzyme responsible for this biosynthesis is HMG CoA reductase, which converts 3 hydroxymethylglutaryl coenzyme A to mevalonate. Biochemical studies have shown that 7α,12α-dihydroxylcholest-4-en-3-one is metabolized by the liver into bile acids and excreted in the urine. This compound has also been shown to be an antiinflammatory agent due to its ability to inhibit prostaglandin synthesis and reduce inflammation.Formule :C27H44O3Degré de pureté :Min. 95%Masse moléculaire :416.64 g/mol5alpha-Androstan-3-one
CAS :Produit contrôlé<p>5alpha-Androstan-3-one is a metabolic intermediate of testosterone. It is found in the urine of humans and other mammals, but at concentrations that are 10 to 100 times lower than those of testosterone. It is also found in some plants and fungi. 5alpha-Androstan-3-one can be synthesized from cholesterol, or it can be formed by the hydroxylation of testosterone in response to the action of cytochrome P450 enzymes. The synthesis of 5alpha-androstan-3-one from cholesterol requires a significant amount of energy, so it is not likely to be a major route for its production. In contrast, the conversion of testosterone to 5alpha-androstan-3-one is an important pathway for maintaining physiological levels of this metabolite. The activity of 5alpha-androstan-3-one has been shown to depend on its concentration in tissues and cells. At low concentrations (less than 10 nM) 5alpha -</p>Formule :C19H30ODegré de pureté :Min. 95%Masse moléculaire :274.44 g/mol
