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.

  • 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>

  • 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>

  • 2-Acetylbenzoic acid

    CAS:
    <p>2-Acetylbenzoic acid is a functional molecule that contains an acetyl group. It can form hydrogen bonds with other molecules and has been shown to induce apoptosis in cells. The reaction products of 2-acetylbenzoic acid are malonic acid, acetylsalicylic acid, and 2-benzoylbenzoic acid. These three compounds are made by the addition of hydrogen or hydroxide to the molecule 2-acetylbenzoic acid. The molecule has two functional groups: a carbonyl group and an acetyl group. The chemical structure of this molecule can be seen in the figure below.<br>2-Acetylbenzoic Acid</p>
