1,3-Dihydroxynaphthalene ≥99.00%, crystalline, Sigma-Aldrich®
Supplier: SIGMA ALDRICH MICROSCOPY
1,3-Dihydroxynaphthalene is a dye intermediate forming stable colors when applied with particular mordants and in mixtures with other oxidising dyes. This specific reagent is intended for the quantitative colorimetric determination of alduronic acids, such as glucuronic acid from urine. The mutagenicity of ozonation derivatives of 1,3-dihydroxynaphthalene against several Salmonella typhimurium strains has been studied.
