The hydroxyl group on this substrate film is susceptible to degradation by acids, which may lead to its chemical instability.Formule :C16H16O3Degré de pureté :Min. 95%Couleur et forme :White To Off-White SolidMasse moléculaire :256.3 g/mol5-Nitrovanillin
CAS :<p>5-Nitrovanillin is a white crystalline solid with a molecular formula of C8H7NO2. It reacts with nucleophilic compounds, such as ammonia, in the presence of heat to produce a molecule containing an oxygen atom and two nitro groups. 5-Nitrovanillin has been found to undergo demethylation when heated in the presence of hydroxylamine. Reaction products include protocatechuic acid, nitromethane, and 5-nitrobenzoic acid. This compound can be identified by its characteristic nmr spectrum that includes a hydroxyl group and a hydrogen bond between the nitrogen atom and the hydroxyl group. The chemical ionization mass spectrometer can also be used to identify 5-nitrovanillin.</p>Formule :C8H7NO5Degré de pureté :Min. 95%Couleur et forme :Yellow PowderMasse moléculaire :197.14 g/molN-Dihydrocinnamoylaminocaproic acid

CAS :4-Methoxy-3-nitrobenzoic acid methyl ester (4MNBM) is a potent antitumor agent that inhibits tumor cell proliferation by interfering with DNA replication. 4MNBM selectively binds to the nuclear magnetic resonance and has been shown to inhibit tumor growth in animal models. This drug also shows potent antitumor activity against solid tumor cells, which is due to its ability to induce conformational changes in the DNA of these cells. 4MNBM has been shown to be selective for tumor cells, which may be due to its lack of effect on the metabolism of normal tissue and its ability to bind to proteins in tumor cell nuclei.Formule :C9H9NO5Degré de pureté :Min. 95%Couleur et forme :Clear LiquidMasse moléculaire :211.17 g/mol4'-Hydroxy-3'-nitroacetophenone
CAS :4'-Hydroxy-3'-nitroacetophenone is a synthetic compound that has been used as an xanthine oxidase inhibitor. It has been shown to reversibly inhibit xanthine oxidase and prevent the accumulation of toxic metabolites that are produced by this enzyme. 4'-Hydroxy-3'-nitroacetophenone also inhibits the activities of other enzymes, such as covalent adducts with protein molecules and transfer reactions. The molecular modeling study of this compound showed that it binds to the active site of xanthine oxidase, forming a covalent adduct between the reactive oxygen species (ROS) and the phenolic OH group on the inhibitor molecule. 4'-Hydroxy-3'-nitroacetophenone was found to be safe in clinical studies, with reversible covalent binding and no inhibition of protein synthesis or cell growth at therapeutic concentrations.Formule :C8H7NO4Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :181.15 g/molRivastigmine hydrochloride

CAS :<p>N-D-Biotinyl-7-amino-4-methylcoumarin is a fluorescent substrate that is used to measure the activity of biotinidase, an enzyme that catalyzes the hydrolysis of biotin. It is detectable by measuring fluorescence with a spectrophotometer. Biotinidase deficiency can be diagnosed by measuring the activity of this enzyme in biological fluids. This assay has been shown to be useful for diagnosing patients with deficient biotinidase activity.</p>Formule :C20H23N3O4SDegré de pureté :Min. 98 Area-%Couleur et forme :PowderMasse moléculaire :401.48 g/mol1-Hydroxy-2-acetonaphthone
CAS :<p>1-Hydroxy-2-acetonaphthone is a molecule that has been shown to have photophysical properties. In a model system, it was shown that 1-hydroxy-2-acetonaphthone can react with proton transfer due to intramolecular hydrogen bonding. This reaction can be used as a fluorescence probe for proton transfer reactions in the presence of cyclohexane rings. The geometry of the molecule is also important for its ability to produce an observable fluorescence signal, with the cyclohexane ring acting as a coordination geometry. Hydrogen bonds are made between the hydroxyl group and other groups on the molecule, which also contribute to its fluorescence characteristics.</p>Formule :C12H10O2Degré de pureté :90%Couleur et forme :Off-White PowderMasse moléculaire :186.21 g/mol
