Application

2-Naphthalenethiol serves as a versatile building block in organic synthesis, particularly in the preparation of sulfur-containing heterocycles and metal-organic frameworks (MOFs). Its thiol group enables facile conjugation to gold surfaces, making it valuable for self-assembled monolayers (SAMs) in nanotechnology and sensor development. Researchers also employ it as a ligand in transition metal catalysis and as a precursor for functionalized naphthalene derivatives in materials science.
