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.

  • 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-Hydrazinobenzoic acid hydrochloride

    CAS :
    <p>4-Hydrazinobenzoic acid hydrochloride is a chemical species that has an oxidative effect on DNA. It is a reactive oxygen species (ROS) that changes the hydrogen spectrum of water. The hydrogen bond is broken and the electrons in the molecule are excited to a higher energy level, which results in ROS formation. 4-Hydrazinobenzoic acid hydrochloride also inhibits mitochondrial function and causes heart disease by increasing blood pressure and weakening the heart muscle. This compound can be used as a cancer treatment for human cells, because it suppresses genes that promote cell growth. In addition, 4-hydrazinobenzoic acid hydrochloride may inhibit endothelial cell proliferation in animal experiments.</p>

  • Methyl 4-amino-2-methoxybenzoate

    CAS :
    <p>Methyl 4-amino-2-methoxybenzoate is a solute with anticancer activity. It has been shown to inhibit the growth of erythrocytes and cancer cells in vitro. The mechanism of action is associated with its ability to bind to aminobenzothiazole, which inhibits the production of DNA and RNA. Methyl 4-amino-2-methoxybenzoate has also been shown to inhibit the proliferation of human muscle cells and induce their differentiation. This drug does not have any effect on lipid or protein synthesis in cells, which may be due to its solvent perturbation properties.</p>

  • 4-Hydrazinobenzoic acid

    CAS :
    <p>4-Hydrazinobenzoic acid is a chemical compound that is used as an inhibitor of DNA synthesis. It prevents the formation of hydrogen bonds between nucleotides in DNA, which prevents the synthesis of new DNA strands. 4-Hydrazinobenzoic acid has been shown to inhibit the growth of human breast cancer cells by reactivating the tumor suppressor genes p21 and Rb1, which are responsible for regulating cell cycle progression. This compound also inhibits the production of hydrogen chloride (HCl) in reaction solutions containing sodium hypochlorite (NaOCl).</p>

  • 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>
