  • Applications

    1-Hydroxy-2-naphthoic acid (CAS 86-48-6) is typically used as an intermediate in the synthesis of pharmaceutical and agrochemical compounds; it also serves as a precursor for dyes and pigments in the specialty colorant sector; in polymer and coating formulations it is explored as a building block for UV-absorbing additives and related stabilizers; the molecule can act as a metal-chelating ligand in catalysis and analytical chemistry; and it provides a versatile building block for preparing functionalized naphthalene derivatives in organic synthesis.
