CAS 40357-96-8: 2-Nitrothiophene-4-carboxylic acid
Description:2-Nitrothiophene-4-carboxylic acid is an organic compound characterized by its thiophene ring, which is a five-membered aromatic heterocycle containing sulfur. The presence of a nitro group (-NO2) at the second position and a carboxylic acid group (-COOH) at the fourth position of the thiophene ring contributes to its chemical reactivity and polarity. This compound typically exhibits properties such as being a solid at room temperature, with potential applications in organic synthesis and as an intermediate in the production of various pharmaceuticals and agrochemicals. The nitro group can participate in electrophilic substitution reactions, while the carboxylic acid group can engage in acid-base reactions and form esters or amides. Additionally, 2-nitrothiophene-4-carboxylic acid may display interesting electronic properties due to the conjugation between the nitro group and the aromatic system, influencing its behavior in chemical reactions and interactions with other molecules. Its solubility in polar solvents is generally higher due to the presence of the carboxylic acid functional group.
