NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing comprehensive information on the chemical compounds we offer. This article focuses on 4-Aminophthalic Acid (CAS 5434-21-9), delving into its detailed chemical profile, which is essential for its effective use as a pharmaceutical intermediate. Understanding these intrinsic 4-aminophthalic acid properties allows chemists to predict its behavior and optimize its application in various synthetic processes.

Chemically, 4-Aminophthalic Acid is characterized by its molecular formula C8H7NO4 and a molecular weight of approximately 181.15 g/mol. Its structure features an aminophenyl group attached to a phthalic acid moiety. This combination of functional groups imparts a dual reactivity, enabling it to participate in reactions characteristic of both amines and carboxylic acids. The presence of the amine group allows for nucleophilic substitution and acylation, while the carboxylic acid groups can undergo esterification, amidation, and salt formation.

The uses of 4-aminophthalic acid are directly linked to this reactivity. It serves as a crucial building block in organic synthesis, particularly in the pharmaceutical industry where it is used to construct complex molecular scaffolds. The ability to selectively functionalize either the amine or the carboxylic acid groups makes it a highly adaptable intermediate. For researchers looking to buy 4-aminophthalic acid, these reactivity patterns are key to unlocking its full potential.

Its physical properties, such as its appearance as an off-white powder and a melting point of around 344 °C (with decomposition), are also important considerations for handling and processing. These characteristics influence storage requirements and the conditions under which it can be effectively reacted.
