Sorbitan monolaurate has been shown to act as an absorption enhancer, which may be due to its ability to form hydrogen bonds with other molecules and its capacity to interact with sodium citrate. Sorbitan monolaurate also has biological properties such as the inhibition of autoimmune diseases, malonic acid production, and bacterial growth.</p>Formule :C18H34O6Degré de pureté :Min. 95%Couleur et forme :Slightly Yellow Clear LiquidMasse moléculaire :346.46 g/mol6-Hydroxycoumarin
CAS :<p>6-Hydroxymethylcoumarin is a reactive, hydroxyl-containing molecule that has been shown to have inhibitory properties against the bacteria Pseudomonas aeruginosa. It is an inhibitor of nucleophilic substitutions, which are necessary for the synthesis of DNA and RNA. 6-Hydroxycoumarin has been shown to be effective in vitro against p. aeruginosa and other bacteria with similar mechanisms of action. Coumarins have also been found to be cytotoxic and cancerous in nature, as well as inhibiting growth factor activity. They are also used as pharmaceutical preparations for treating gastric ulcers due to their ability to inhibit the production of hydrochloric acid by parietal cells in the stomach lining.</p>Formule :C9H6O3Degré de pureté :Min. 95 Area-%Couleur et forme :PowderMasse moléculaire :162.14 g/molFmoc-L-homotyrosine
CAS :<p>Fmoc-L-homotyrosine is a tyrosine kinase inhibitor. Tyrosine kinases are enzymes that catalyze the transfer of phosphate groups from ATP to tyrosine residues in proteins, which play a role in many cellular processes. Fmoc-L-homotyrosine binds to the ATP binding site in the active site of these enzymes, preventing phosphorylation and thus preventing protein function. This compound has been shown to inhibit neurotensin receptors in vitro and has also been shown to be an endogenous ligand for this receptor. Fmoc-L-homotyrosine binds to allosteric sites on the neurotensin receptor, causing conformational changes that activate transduction pathways and increase signaling. The mechanism of inhibition is not yet fully understood but is thought to be due to steric hindrance or allosteric binding.</p>Formule :C25H23NO5Degré de pureté :Min. 95%Masse moléculaire :417.45 g/molD-a-Tocopherol

CAS :<p>4'-Methylacetophenone is a solvent that is used in the chemical industry, mainly for the production of trifluoroacetic acid. It has also been shown to be an effective antimicrobial agent, which is due to its ability to dissolve lipids and proteins. The mechanism of action of 4'-methylacetophenone is not fully understood, but it has been suggested that this compound reacts with fatty acids and pyrazole rings in the cell membrane and disrupts lipid bilayers. 4'-Methylacetophenone can be used as a reagent for solid phase microextraction in analytical chemistry. In addition, it reacts with acidic compounds (e.g., sulfuric acid) to produce insoluble salts and can be used as an analytical method for determining the concentration of these compounds.</p>Formule :C9H10ODegré de pureté :Min. 95%Couleur et forme :Clear LiquidMasse moléculaire :134.18 g/mol1-Naphthol-4-sulfonic acid
CAS :<p>1-Naphthol-4-sulfonic acid is a compound that is used as an analytical reagent. It can be synthesized by heating 1-naphthol with concentrated sulfuric acid in the presence of a polymerization initiator. The reaction produces 1,4-dioxane, which is then converted to 1-naphthol-4-sulfonic acid by hydrolysis with deionized water and hydrochloric acid. The analytical reagent has been used for the analysis of impurities in polymers, such as trifluoroacetic acid, and for wastewater treatment. Radiation causes the release of light emission from 1-naphthol-4-sulfonic acid, making it useful for determining the level of nitrite ion in wastewater. This chemical has also been found to react with sulfamate ions to produce structural formula (SO2)2NH3.</p>Formule :C10H8O4SDegré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :224.23 g/mol2-Bromo-3'-bromoacetophenone
CAS :<p>2-Bromo-3'-bromoacetophenone is a chemical compound that can be used as an oxidant in organic synthesis. It is a brominated phenol derivative, which undergoes bond cleavage to produce benzoylbenzene and acetone. The reaction is mediated by potassium permanganate in the presence of oxygen. X-ray crystallography and crystallography have been used to identify the molecular structure of 2-bromo-3'-bromoacetophenone. The yield for this reaction is high and can be increased by using solvents such as ethanol or tetrahydrofuran and a reaction time of 1 hour at 100°C.</p>Formule :C8H6Br2ODegré de pureté :Min. 90%Masse moléculaire :277.94 g/molTropine
CAS :<p>Tropine is a natural alkaloid that is derived from plants in the Solanaceae family including Atropa belladonna and Hyoscyamus niger. Tropine has been shown to have a number of physiological effects, including receptor binding, enzyme activities, and physiological effects. It has been used as an analytical method for determining sodium citrate, nitrogen atoms, and ester linkages. Tropine also has a ph optimum of 9-10 which means it should be dissolved in acidic solutions or diluted with a buffer solution before use. The reaction mechanism of tropine is not yet known, but it has been shown to contain fatty acid groups that are intramolecularly hydrogenated.</p>Formule :C8H15NODegré de pureté :Min. 95%Couleur et forme :White PowderMasse moléculaire :141.21 g/mol
