## Abstract A sensitive HPLC‐fluorescence (FL) method with FL‐labeling reagent for simultaneous determination of 1‐ and 2‐naphthol was developed. The FL‐labeling reaction of naphthols with 4‐(4,5‐diphenyl‐1__H__‐imidazol‐2‐yl)benzoyl chloride (DIB‐Cl) was completed in 20 min at 40°C. The separation
