应用
2-Naphthoic acid is an unprotected acid undergoes lithiation, e.g. with s-BuLi, by stereospecific 1,4-addition, providing a facile route to 1,2,2-trisubstituted 1,2-dihydronaphthalenes. It is also used as an intermediate in organic synthesis. The fluorescence spectra and electronic absorption of 2-naphthoic acid was studied.

备注
Keep container tightly closed in a dry and well-ventilated place. Keep away from oxidizing agents.
