| Hazard Information | Back Directory | [Description]
2,3-Naphthalenedicarboxylic acid, also known as 2,3-naphthalic acid, belongs to the class of organic compounds known as naphthalenecarboxylic acids. Naphthalenecarboxylic acids are compounds containing a naphthalene moiety that bears a carboxylic acid group in one or more positions. Naphthalene is a bicyclic compound that is made up of two fused benzene rings. 2,3-Naphthalenedicarboxylic acid is an important chemical intermediate with important applications in fine chemicals. It can be used as a raw material or intermediate for synthesizing liquid crystal display materials, medicines, pesticides, spices, and inks.
