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-Chlorobenzonitrile
CAS :<p>2-Chlorobenzonitrile is a white solid that is soluble in organic solvents. It is an aryl halide and has a chemical structure of C6ClCN. 2-Chlorobenzonitrile is used as a raw material for the production of dyes and pharmaceuticals. This compound reacts with hydrochloric acid to form 4-chlorobenzonitrile, which can be used in the synthesis of other chemicals. 2-Chlorobenzonitrile can also react with n-dimethyl formamide in an optimal reaction solution to form 4-chlorobenzonitrile. The FTIR spectroscopy on this compound shows that it has a chloride group at 795 cm−1. The optimum reaction temperature for this compound is between 100 and 120 °C, but it will react with inorganic acids such as sulfuric acid or phosphoric acid at higher temperatures. Synthesis of this compound can be done by reacting</p>Formule :C7H4ClNDegré de pureté :Min. 95%Couleur et forme :White PowderMasse moléculaire :137.57 g/molMethyl 3,4-dimethoxybenzoate
CAS :<p>Methyl 3,4-dimethoxybenzoate is an acetate extract that has been shown to inhibit tyrosinase activity. This compound also has a potent inhibitory effect on the production of p-hydroxybenzoic acid. Methyl 3,4-dimethoxybenzoate can be synthesized from protocatechuic acid and methoxy groups. It is a chemical reaction involving three steps: condensation, dehydration, and reduction. Tyrosinase is an enzyme in the melanin biosynthetic pathway that catalyzes the conversion of tyrosine to dopaquinone. Tyrosinase activity can be inhibited by methyl 3,4-dimethoxybenzoate through competitive inhibition or by its ability to reduce the availability of substrate for this enzyme.</p>Formule :C10H12O4Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :196.2 g/mol2-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>Formule :C7H5IO2Degré de pureté :Min. 98 Area-%Couleur et forme :PowderMasse moléculaire :248.02 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/mol3,5-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/mol2,6-Dimethoxy-4-hydroxybenzylamine
