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.
