    Fluorescent Dye Others
    Methyl red is a pH-sensitive acid-base indicator and colorimetric reagent with a pKa of 5.1. Methyl red achieves visual judgment of the titration endpoint through reversible structural changes of protonation (red, pH <4.4) and deprotonation (yellow, pH >6.2). Methyl red is widely used in acid-base titration in chemical analysis and buffer pH monitoring in biochemistry .

    Biochemical Assay Reagents Metabolic Disease
    Dithizone can be toxic to pancreatic islet cells and cause experimental diabetes. Dithizone can be used for in vitro in vivo staining of transplanted islets and cytoplasmic granules of bone marrow cells. Dithizone can be used as a chelating agent and colorimetric indicator for the detection and extraction of various heavy metals, including lead and mercury, in analytical and biochemical applications. Dithizone forms stable colored complexes with metal ions and can be quantitatively analyzed by methods such as spectrophotometry .
