Benzènes
Les benzènes sont des hydrocarbures aromatiques simples constitués d'un anneau de carbone à six membres avec des doubles liaisons alternées. Cette structure fondamentale est un bloc de construction pour de nombreux composés chimiques, y compris les produits pharmaceutiques, les polymères et les colorants. Les benzènes sont largement utilisés en synthèse organique en raison de leur stabilité et de leur polyvalence. Chez CymitQuimica, nous offrons une large gamme de benzènes de haute qualité pour soutenir vos recherches et applications industrielles.

3,5-Dimethylbenzaldehyde
CAS :<p>3,5-Dimethylbenzaldehyde is an organic compound that is a colorless liquid. It has a chemical formula of C9H12O2 and is classified as an aldehyde. 3,5-Dimethylbenzaldehyde can be synthesized by the reaction of isopropyl palmitate with xylene in the presence of carbon as a source. The reaction time required for this synthesis is approximately one day. The major products of this reaction are 3,5-dimethylbenzaldehyde and 2-methylbutanal. This reaction mechanism can also be used to determine the concentration of urinary metabolites in human urine samples. Analysis of these samples requires an organic solvent such as hexane or dichloromethane. Kinetic data was collected from the rate at which zinc powder reacts with 3,5-dimethylbenzaldehyde over time at different concentrations. A kinetic experiment was conducted using c–h bond activation to produce 3,5-dimethoxy</p>Formule :C9H10ODegré de pureté :Min. 95%Couleur et forme :Colorless Clear LiquidMasse moléculaire :134.18 g/mol4-tert-Butoxybenzaldehyde
CAS :<p>4-tert-Butoxybenzaldehyde is a colorless liquid that has a viscosity of 0.3 mm2/s at 25 °C. It can be synthesized by reacting pyridine with hydrochloric acid in the presence of a Grignard reagent. 4-tert-Butoxybenzaldehyde reacts with phenolic antioxidants to form an ester, which can be used as an industrial solvent. The crystal x-ray diffraction pattern of 4-tert-Butoxybenzaldehyde exhibits peaks at 2θ = 8.0, 11.5, and 18.5° corresponding to the (100), (200), and (220) planes, respectively. This chemical can also undergo reactions that lead to termination or transfer reactions, including diethyl ketomalonate formation with diethyl malonate in the presence of water as a solvent and potassium hydroxide as a catalyst for transfer reactions.END></p>Formule :C11H14O2Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :178.23 g/molMethyl 3-bromobenzoate
CAS :<p>Methyl 3-bromobenzoate is a cross-coupled compound with three functional groups: a methyl group, an acid bromo group, and a carboxylic acid benzoic ester. It is used in the synthesis of antigens that are chemically reactive to trifluoroacetic acid gas. The clinical studies have shown that the efficiency of this study is low because it has been found to be difficult to synthesize methyl 3-bromobenzoate in large quantities. This molecule can be prepared by the reaction of vinylene with an electrophile in non-polar solvents or by catalytic mechanisms.</p>Formule :C8H7BrO2Degré de pureté :Min. 95%Couleur et forme :White PowderMasse moléculaire :215.04 g/mol2-Methyl-5-nitrobenzaldehyde
CAS :<p>2-Methyl-5-nitrobenzaldehyde is a nitro compound that is used in the synthesis of dobutamine. It has been shown to undergo rearrangements, with the formation of 2-methyl-5-nitrophenol. Kinetic studies have shown that chlorine can be substituted for hydrogen at the 2 position, and this substitution leads to an increase in reactivity. 2-methyl-5-nitrobenzaldehyde also reacts with dopamine to form a ketone. The hydroxy group on this molecule is nucleophilic and can attack electrophiles, making it useful as an active site for synthetic reactions. This compound is also pyrophoric, which means it will spontaneously ignite in air and burn until all its fuel is consumed.</p>Formule :C8H7NO3Degré de pureté :Min. 95%Couleur et forme :Off-White PowderMasse moléculaire :165.15 g/mol2,6-Dimethoxy-4-hydroxybenzylamine
