  • Applications

    Xanthydrol (CAS 90-46-0) is primarily used as an intermediate in the synthesis of xanthene-based dyes and pigments, acting as a precursor for colorants in coatings, inks, and plastics. It is employed as a colorimetric reagent for carbonyl-containing compounds, enabling routine analytical monitoring in industrial and chemical-analysis contexts. The compound also serves as a building block for fluorescent dyes and probes used in research and analytical applications. In materials science, xanthydrol can function as a color-forming precursor for coloring and pigmentation of polymers, contributing to coloration and optical properties in a range of products.
