1-Naphthoic acid Usage And Synthesis

Chemical Properties

Off-white to beige powder

Uses

1-Naphthoic acid is used as an intermediate for the synthesis of pharmaceuticals, photochemicals, plant growth hormones, dyes and other organic compounds.

Definition

ChEBI: 1-naphthoic acid is a naphthoic acid carrying a carboxy group at position 1. It has a role as a fungal xenobiotic metabolite and a bacterial xenobiotic metabolite. It is a conjugate acid of a 1-naphthoate.
