Product Description:

Chloranilic acid, also known as 2,5-dichloro-3,6-dihydroxy-1,4-benzoquinone, is a purple crystalline solid. It is a derivative of benzoquinone and exists in equilibrium with its tautomeric forms. Its primary application is as a sensitive colorimetric reagent and indicator in analytical chemistry. It forms intensely colored complexes with various metal ions, including magnesium, calcium, strontium, barium, and lead, which is utilized for their detection and quantitative determination. It also serves as a redox indicator in titrimetric analysis due to its distinct color change between oxidized and reduced states. Furthermore, chloranilic acid can act as a mild oxidizing agent in certain organic synthesis reactions. The compound is commercially available as an analytical reagent grade chemical. It is considered harmful if swallowed and causes skin and eye irritation, requiring appropriate safety precautions during handling.
