CAS:<p>3',5'-Dichloro-2'-hydroxyacetophenone is a hydrogen bond donor and has a crystal system of orthorhombic. It is soluble in water and insoluble in organic solvents. 3',5'-Dichloro-2'-hydroxyacetophenone binds to the progesterone receptor, which is a nuclear hormone receptor that regulates gene transcription by binding to specific DNA sequences called hormone response elements. There are two cleavage products of progesterone receptor, Malondialdehyde (MDA) and estradiol (E2). 3',5'-Dichloro-2'-hydroxyacetophenone also binds to estrogen receptors, which are proteins located inside or on the surface of cells that bind to hormones and regulate the activity of certain genes. The biochemical function of 3',5'-dichloro-2' hydroxyacetophenone is not well understood but it has been shown to have antioxidant properties.</p>Fórmula:C8H6Cl2O2Pureza:Min. 95%Peso molecular:205.04 g/mol4-Isobutylcinnamic acid
CAS:<p>4-Isobutylcinnamic acid is an organic compound that is a derivative of the organic compound acrylic acid. It is an organic ester, which means it is formed by the reaction of an alcohol and an acid. Acrylic acid can be reacted with either ethyl alcohol or isobutyl alcohol to produce 4-isobutylcinnamic acid. The resulting product can be used in the production of polymers and plastics.</p>Fórmula:C13H16O2Pureza:Min. 95%Cor e Forma:PowderPeso molecular:204.26 g/mol4,4',6,6'-Tetramethyl-2,2'-bipyridine
CAS:<p>4,4',6,6'-Tetramethyl-2,2'-bipyridine (TMTB) is a small molecule that can be used as an efficient and cost-effective catalyst for the production of hydrogen from water. TMTB is able to transform solar energy into chemical energy by converting light absorbed in a semiconductor material to an electric current. TMTB has been shown to improve the efficiency of solar cells by boosting the performance of the catalysts that drive chemical reactions in the devices. This effect was found to be synergistic with other materials such as graphene oxide and tungsten disulfide. In addition, TMTB nanoparticles were shown to have a normalizing effect on the charge density in photoelectrochemical cells, which may lead to improved stability and durability.</p>Fórmula:C14H16N2Pureza:Min. 95 Area-%Cor e Forma:PowderPeso molecular:212.30 g/mol6-Bromo-2-naphthol
