Benzeni

I benzene sono semplici idrocarburi aromatici costituiti da un anello di carbonio a sei membri con doppi legami alternati. Questa struttura fondamentale è un blocco costitutivo per numerosi composti chimici, inclusi prodotti farmaceutici, polimeri e coloranti. I benzene sono ampiamente utilizzati nella sintesi organica grazie alla loro stabilità e versatilità. Presso CymitQuimica, offriamo un'ampia gamma di benzene di alta qualità per supportare le vostre ricerche e applicazioni industriali.

  • Methyl 3,4-dimethoxybenzoate

    CAS:
    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.

  • 4,6-Dimethoxysalicylaldehyde

    CAS:
    4,6-Dimethoxysalicylaldehyde is a protonated molecule with a cyclohexane ring and 4 hydroxyl groups. Its chemical formula is C6H8O3. The compound has low bioavailability due to the presence of an intramolecular hydrogen bond that causes high redox potential. There are two amines on the aromatic ring which can coordinate with metal ions to form a complex. This compound's structural analysis has been conducted using X-ray crystallography, NMR spectroscopy, and IR spectroscopy. The structure of 4,6-dimethoxysalicylaldehyde is unsymmetrical due to the presence of two asymmetric carbon atoms in the molecule. It forms hydrogen bonds with other molecules due to its hydroxyl group and intramolecular hydrogen bond. Hydrogen bonding interactions occur between this compound and other molecules including water, alcohols, ammonia, amines, and carboxylic acids.

  • 4-Bromobenzaldehyde

    CAS:

    4-Bromobenzaldehyde is a chemical compound that belongs to the group of aromatic compounds. It has been shown to have a potent stimulatory effect on locomotor activity in mice, which may be due to its ability to increase levels of epidermal growth factor and gamma-aminobutyric acid in the brain. 4-Bromobenzaldehyde can be synthesized from 2,4-dibromophenol and anhydrous copper chloride in the presence of sodium hydroxide. The reaction mechanism for this synthesis is believed to involve an intermediate enamine form of 4-bromobenzaldehyde, which can then undergo hydrolysis into 2,4-dibromophenol and benzaldehyde. This product is used as a reagent in organic synthesis because it can be used to form esters with trifluoroacetic acid or hydrochloric acid in high yield.

  • 2-Hydroxy-6-methylbenzoic acid

    CAS:

    2-Hydroxy-6-methylbenzoic acid is a natural product that is synthesized by the enzyme p. pastoris. It is a member of the polyketide class of compounds and has shown to have physiological effects such as anti-inflammatory and antioxidant properties. 2-Hydroxy-6-methylbenzoic acid also has been shown to inhibit ATP binding cassette transporter (ABC) proteins, which are involved in drug resistance, from transporting drugs out of cells, making it an attractive candidate for drug discovery.
