Benzènes

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.

  • 2-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>

  • 4-Formylbenzoic acid

    CAS :
    <p>4-Formylbenzoic acid is an organic compound with the molecular formula CH2=C(O)CH=CHCO2H. It is a white solid that is soluble in water and has a strong, unpleasant odor. 4-Formylbenzoic acid has been shown to have affinity for binding to odorous molecules such as sulfur compounds, amines, and mercaptans. The binding of these molecules to the 4-formylbenzoic acid leads to a decrease in their odor concentration. This process can be done using electrochemical impedance spectroscopy or optical sensors. The oxidation of 4-formylbenzoic acid by trifluoroacetic acid produces 2-formylphenol and formaldehyde, which are themselves volatile compounds with an unpleasant odor. These reactions may be used as wastewater treatment methods. Langmuir adsorption isotherm may be used as an analytical method for measuring the concentration of 4-formylbenzoic acid</p>

  • 3,5-Dihydroxybenzaldehyde

    CAS :
    <p>3,5-Dihydroxybenzaldehyde (DHBA) is a plant metabolite that is classified as a phenolic compound. It is found in many plants and has important biological functions such as the production of carotenoids or the cleavage of carotenoid to form other compounds. DHBA can be extracted from plant tissue with hydrochloric acid or carbon sources. It has been shown that DHBA inhibits the growth of soil bacteria by binding to amines and thus preventing them from reacting with substrates. This may be due to its ability to act as an electron donor, which could also explain its inhibitory activity on carotenoid cleavage.</p>

  • 4-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&gt;</p>

  • Methyl 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>

  • 2-Iodobenzoic acid

    CAS :
    <p>2-Iodobenzoic acid is a synthetic compound that is used in the treatment of wastewater. It is produced by the reaction of benzoate and nitrite in the presence of sodium hydroxide. The intramolecular hydrogen atom transfer from the 2-iodobenzoic acid to benzoate is a reversible reaction. This process can be catalyzed by palladium, which has been shown to be effective in coupling 2-iodobenzoic acid with other compounds to produce cyclic peptides. The use of 2-iodobenzoic acid as a contraceptive has been investigated for its ability to inhibit acetylcholinesterase activity, which may lead to increased levels of acetylcholine and inhibition of muscle contractions.</p>
