Naphthalenes

4-Amino-3-hydroxy-1-naphthalenesulfonic acid is used as a key starting material for the preparation of naphthalenesulfonic acid derivatives by reacting with palmitoyl chloride, which shows the activity to inhibit DNA polymerase and ribonuclease H Activities of HIV-1 reverse transcriptase. It is also used to prepare a copolyner with melamine, which is associated with graphene to prepare molecularly imprinted sensor and utilized for the determination of melatonin in human biological fluids.

Naphthalene-1,4,5,8-tetracarboxylic dianhydride is a molecule that contains two carboxylic acid groups and one tetracarboxylic acid group. It is an adsorbent material that is used to remove water vapor from the atmosphere. Naphthalene-1,4,5,8-tetracarboxylic dianhydride is also used in wastewater treatment processes because it has high chemical stability and can be regenerated with anhydrous sodium. The transport properties of naphthalene-1,4,5,8-tetracarboxylic dianhydride are well suited for use as a model system for studying the kinetics of proton exchange membrane fuel cells (PEMFC). This compound has been studied using electrochemical impedance spectroscopy to determine its kinetic data.
