Solvants non polaires
Les solvants non polaires sont une classe de solvants qui dissolvent les composés non polaires en raison de leurs faibles constantes diélectriques et de l'absence de charges partielles significatives. Ils sont largement utilisés dans divers processus chimiques et applications, y compris la synthèse organique, les extractions et la chromatographie. Les solvants non polaires courants incluent des substances avec des anneaux à 6 membres et des Building Blocks tels que l'hexane et le toluène, qui sont cruciaux pour dissoudre les composés hydrophobes. Ces solvants jouent un rôle essentiel dans la préparation d'ingrédients pharmaceutiques actifs (APIs) et de composés de recherche connexes. De plus, les solvants non polaires sont utilisés en spectroscopie RMN, où ils aident à dissoudre les analytes non polaires sans interférer avec l'analyse spectrale. Ils sont également importants dans les processus impliquant des acides aminés, des composés organiques chlorés et divers Building Blocks. Leur efficacité à dissoudre les composés organiques rend les solvants non polaires indispensables dans les environnements de laboratoire et industriels.

CAS :2,4,6-Trinitrobenzenesulfonic acid (also known as TNBS, TNSBA or picrylsulfonic acid) is a strongly oxidising organic acid that has long been used as a reagent to determine the presence of free primary amine groups. TNBS reacts rapidly with primary amines to form highly coloured N-trinitrophenyl acid products which can then be analysed by colorimetry. The amine can be regenerated by treatment with hydrazine. This analytical technique can also be applied to thiols and hydrazides. As is common with nitrated aromatic compounds, there is a risk of explosion and TNBS is typically commercially available as a solution. We also supply the 1% solution in DMF.Formule :C6H3N3O9SCouleur et forme :Colorless Yellow Clear LiquidMasse moléculaire :293.17 g/molRef: 3D-FT73268

CAS :<p>2-Bromo-5-methoxytoluene is a synthetic organic compound that is used as a chemical intermediate for cellulose derivatives. It is generated by the Friedel-Crafts reaction of bromine with toluene in the presence of aluminum chloride. 2-Bromo-5-methoxytoluene has been shown to react with cellulose derivatives and other hydrogen bond acceptors. This reaction is followed by protonation, which yields a chromophore that changes color from yellow to orange. The mechanism of this reaction can be explained by an acid catalysis mechanism, which begins with protonation of the carbonyl group (C=O) and formyl group (HC=O) groups. This causes the formation of an enolate ion, which reacts with a protonated carbonyl group to yield a formyl cation and an enolate ion. The formyl cation then reacts with another proton</p>Formule :C8H9OBrDegré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :201.06 g/molAzobenzene
CAS :<p>Azobenzene is an azobenzene that binds to the actin filaments and inhibits their polymerization. It has been shown to inhibit the polymerization of actin filaments in human serum, which may be due to its ability to react with the nitrogen atoms in actin. Azobenzene has also been shown to have a thermal expansion coefficient of 0.015x10-5/°C, which is much larger than that of most other compounds. The molecular geometry of azobenzene is planar and symmetrical, with two hydrogen atoms on each nitrogen atom on both sides of the molecule. This symmetry leads to a low intramolecular hydrogen bonding energy. The molecule’s photochemical properties are also interesting because it has a long lifetime and can be excited by wavelengths between 400-500 nm.</p>Formule :C12H10N2Degré de pureté :Min. 97.5 Area-%Couleur et forme :PowderMasse moléculaire :182.22 g/mol1,3-Benzenedialdehyde
