Cetonas

As cetonas são compostos orgânicos caracterizados pela presença de um grupo carbonilo (C=O) ligado a dois átomos de carbono. Esses compostos são altamente versáteis e desempenham um papel crucial em várias reações químicas, incluindo oxidação, redução e condensação. As cetonas são intermediários essenciais na síntese de produtos farmacêuticos, fragrâncias e polímeros. Na CymitQuimica, oferecemos uma ampla gama de cetonas de alta qualidade para apoiar suas aplicações de pesquisa e industriais.

    CAS:
    <p>5-Bromo-6-methylpyrimidine-2,4(1H,3H)-dione is an immunosuppressive drug that belongs to the class of hydantoins. It can be used to treat a variety of diseases associated with immunodeficiency including AIDS. 5-Bromo-6-methylpyrimidine-2,4(1H,3H)-dione inhibits viral replication by alkylating nucleotides and DNA synthesis at the GTPase level. The amide group in the molecule is responsible for this property. Kinetics studies have shown that the rate of hydrolysis of 5-bromo-6-methylpyrimidine-2,4(1H,3H)-dione depends on the pH and temperature of solution.</p>

  • 5α-Androstan-3-one

    Produto Controlado
    CAS:
    <p>5alpha-Androstan-3-one is a metabolic intermediate of testosterone. It is found in the urine of humans and other mammals, but at concentrations that are 10 to 100 times lower than those of testosterone. It is also found in some plants and fungi. 5alpha-Androstan-3-one can be synthesized from cholesterol, or it can be formed by the hydroxylation of testosterone in response to the action of cytochrome P450 enzymes. The synthesis of 5alpha-androstan-3-one from cholesterol requires a significant amount of energy, so it is not likely to be a major route for its production. In contrast, the conversion of testosterone to 5alpha-androstan-3-one is an important pathway for maintaining physiological levels of this metabolite. The activity of 5alpha-androstan-3-one has been shown to depend on its concentration in tissues and cells. At low concentrations (less than 10 nM) 5alpha -</p>

    <p>3-(2-Bromoacetyl)-2H-chromen-2-one is a compound that has been shown to inhibit the growth of human liver cancer cells and has been used in the treatment of some cancers. 3-(2-Bromoacetyl)-2H-chromen-2-one is a nucleophile, which reacts with electrophiles, such as 2Nal, to form an intermediate covalent bond. The reaction mechanism for this process involves a nucleophilic substitution reaction, where one atom (the nucleophile) attacks another atom (the electrophile) from the side opposite its electron cloud. This process results in the formation of a covalent bond between the two atoms and the release of water. 3-(2-Bromoacetyl)-2H-chromen-2one was found to be effective against Streptococcus faecalis and other bacteria after being tested in vitro with these organisms.

  • 3-Methylcyclopentanone

    CAS:
    <p>3-Methylcyclopentanone is a chiral compound that can be prepared by the asymmetric synthesis of 3-methylpentan-2-one. The chemical analyses of 3-methylcyclopentanone have been found to have a dry weight of 136.19 g/mol, with a molecular formula of C5H7O2. 3-Methylcyclopentanone can be identified by its hydrogen bonding interactions and hydroxyl group (-OH). The photoelectron spectrum shows the presence of an intramolecular hydrogen bond between the -OH group and one of the methyl groups. This intramolecular hydrogen bond is responsible for the high boiling point and low reactivity. This molecule has an a-type configuration, which gives it a higher mass analyzer peak at m/z = 166 than for other configurations, such as b or c.
