CAS :(-)-B-Chlorodiisopinocampheylborane is a carbonyl group that can be used for asymmetric synthesis. It was synthesized from the reaction of chlorodiisopinocampheylborane with butyllithium and allyl bromide, followed by aqueous workup. The enantiomers were separated through thin layer chromatography on silica gel plates with hexane as the eluent. The resolution of racemic latanoprost lactol was achieved in the same manner. (-)-B-Chlorodiisopinocampheylborane is also a diketone that can be prepared from para-chloroacetophenone and sodium hydroxide in ethanol. This diketone undergoes an intramolecular cyclization to produce noradrenaline (norepinephrine) and hydrochloric acid, which can then be converted into dioxolanes or other products.Formule :C20H34BClDegré de pureté :Min. 95%Couleur et forme :Clear LiquidMasse moléculaire :320.75 g/mol2-(Benzylmethylamino)-3',4'-dihydroxyacetophenone

CAS :3-(1-Naphthyl)propyl]amine is an organic compound that is a colorless solid with a melting point of -118°C. It is soluble in water, methanol, and acetone. 3-(1-Naphthyl)propyl]amine forms acid when heated with concentrated hydrochloric acid. The reaction produces hydrogen chloride gas and benzoic acid as a byproduct. 3-(1-Naphthyl)propyl]amine also reacts with pyridine to produce carbamic acid and ammonia gas as a byproduct. This can be rationalized systematically by the loss of the amine group from the nitrogen atom of the amine molecule. Carbamic acid has two acidic protons on it which are stabilized by the carbonyl group on the other side of the molecule. 3-(1-Naphthyl)propyl]amine can also react with anions such as carbonate ions to form carbamate salts,Formule :C13H15NDegré de pureté :Min. 95%Couleur et forme :Clear LiquidMasse moléculaire :185.26 g/mola,O-Dimethyl serotonin
CAS :Produit contrôlé<p>a,O-Dimethyl serotonin is a monoamine compound that is synthesized by the enzymatic decarboxylation of 5-hydroxytryptophan. It has been shown to increase dopamine levels and inhibit the enzyme activity of serotonin in mice. This drug also binds to 5-ht2 receptors and induces the release of serotonin from nerve cells. A linear calibration curve was obtained using bufotenin as a standard. This drug has been used in analytical toxicology for determining the uptake of serotonin into human lung tissue and its effect on 5-ht1a receptors. In addition, a study was conducted with perennial ryegrass to determine whether this drug inhibits plant toxin synthesis. The results showed that it did not have an inhibitory effect on plant toxins and may even promote their synthesis.</p>Formule :C12H16N2ODegré de pureté :Min. 95%Masse moléculaire :204.27 g/molCholesterol Isopropyl Carbonate
