High quality 1,8-Naphthalic anhydride CAS 81-84-5 with factory price
1,8-Naphthalic anhydride is an organic compound with the formula C₁₀H. It is one of three isomers of naphthalic anhydride, the other two being the 1,2- and the 2,3-derivatives. The 1,8-isomer is prepared by aerobic oxidation of acenaphthene. 2,6-naphthalenedicarboxylic acid can be prepared from this anhydride.

1,8-Naphthalic anhydride is a precursor to the 4-chloro and 4,5-dichloro derivatives. These chloride groups are susceptible to displacement by amines and alkoxides, giving rise, ultimately, to a large family of naphthalimides, which are used as optical brighteners.
