The product can be isolated using a solvent extraction technique or purified using column chromatography.Fórmula:C7H6O4Pureza:Min. 98 Area-%Cor e Forma:PowderPeso molecular:154.12 g/mol4-Acetamido-2'-amino-2-nitrophenyl sulphide

CAS:2',4'-Dimethylacetophenone is an acetylating agent that can be used in organic synthesis. It is a chiral compound, which means it has two enantiomers with different properties. The racemic mixture of 2',4'-dimethylacetophenone degrades to form 2-chloro-2',4'-dimethoxybenzene and 2,4-dimethoxybenzoic acid. The reaction time for the formation of these products depends on the concentration of the reactants as well as the acid catalyst used. The Friedel-Crafts acylation occurs when an acetylated phenol reacts with an alkyl halide in the presence of an acid catalyst. This reaction produces a diketone and an alkyl halide, which can then undergo a second Friedel-Crafts acylation with another acetylated phenol. Acetylation also methylates ketones to produce methyl ketones.refFórmula:C10H12OPureza:Min. 95%Cor e Forma:Colorless Clear LiquidPeso molecular:148.2 g/molRetinylaldehyde
CAS:Retinylaldehyde is a derivative of vitamin A that is important for visual health. It is an inhibitor of the chloride channel, which may be due to its ability to inhibit alcohol dehydrogenase and polymerase chain reaction (PCR). Retinylaldehyde has been shown to have a high affinity for nuclear DNA and can bind to guanine nucleotide-binding protein (G protein) in neural cells. This activity leads to chronic cough in mice. Retinylaldehyde also has been shown as having significant up-regulation in human monocytes when exposed to toll-like receptor ligands. The role of retinylaldehyde in the immune system is not fully understood, but it may play a role in modulating the response to bacterial infection by altering the production of cytokines such as interleukin-1β (IL-1β) and tumor necrosis factor alpha (TNFα).Fórmula:C20H28OPureza:Min. 98 Area-%Cor e Forma:PowderPeso molecular:284.44 g/mol3,5-Dimethyl-4-nitropyridine 1-oxide
CAS:3,5-Dimethyl-4-nitropyridine 1-oxide is a nitro compound with the chemical formula CHNO.

CAS:2-Amino-5-bromo-2'-chlorobenzophenone (2ABPC) is an aniline derivative that induces a reversible inhibition of the NMDA receptor. This agent has been shown to inhibit glutamate binding and to have a high affinity for the NMDA receptor. 2ABPC is also able to inhibit cancer growth by binding and neutralizing the receptors that allow for ligand-mediated activation of the NMDA receptor. 2ABPC has been shown to be effective in preventing dorsal root ganglia from developing into cancerous cells, which may be due to its ability to bind receptors that are involved in cell proliferation.Fórmula:C13H9BrClNOPureza:Min. 95%Cor e Forma:SolidPeso molecular:310.57 g/molFluvastatin
CAS:Fluvastatin is a statin that lowers blood cholesterol and triglycerides by inhibiting HMG-CoA reductase, an enzyme that plays a critical role in the synthesis of cholesterol. Fluvastatin has also been shown to reduce the incidence of myocardial infarction, and to reduce atherosclerotic lesions in animal models, reducing the incidence of cardiovascular disease. Fluvastatin also has been shown to inhibit the activation of toll-like receptor 4 (TLR4) by lipopolysaccharide (LPS), which may be related to its anti-inflammatory effects. Furthermore, through lowering blood cholesterol, Fluvastatin also inhibits tubulointerstitial injury and prevents renal damage caused by high concentrations of the lipid.
