CAS 5434-21-9

4-Aminophthalic acid

Description:

4-Aminophthalic acid, with the CAS number 5434-21-9, is an organic compound that belongs to the class of phthalic acids. It features an amino group (-NH2) and two carboxylic acid groups (-COOH) attached to a phthalic acid backbone, specifically at the 4-position relative to the carboxylic acid groups. This compound is typically a white to off-white crystalline solid that is soluble in water and polar organic solvents. It exhibits properties such as being a weak acid due to the presence of carboxylic groups, and it can participate in various chemical reactions, including amination and esterification. 4-Aminophthalic acid is often used in the synthesis of dyes, pharmaceuticals, and agrochemicals, owing to its functional groups that allow for further chemical modifications. Additionally, it may serve as an intermediate in the production of other chemical compounds, making it valuable in industrial applications. Safety data should be consulted for handling and exposure guidelines, as with any chemical substance.

4-Aminophthalic acid is a dibutyl ester of 4-aminophenol. It is used as a substrate for the production of monoclonal antibodies (MABs) to amines or acylation reactions with fatty acids. The MABs can be used in immunoassays to measure the presence of amines and acylated fatty acids in blood samples. The reaction between 4-aminophthalic acid and p-hydroxybenzoic acid forms an ester that can be detected by magnetic resonance spectroscopy, which makes it useful for detecting p-hydroxybenzoic acid levels in urine samples.
