  • 2-Methyl-5-nitrobenzaldehyde

    CAS:

    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.

  • 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.

  • 3,5-Dihydroxybenzaldehyde

    CAS:

    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.
