Application :

• Hydroxy naphthol blue disodium salt is commonly used as an indicator in complexometric titrations, particularly for the determination of metal ions like calcium, magnesium, and zinc. It changes color at pH range 12-13 from blue to reddish pink, in the presence of calcium ions and to deep blue in the presence of disodium ethylenediaminetetraacetic acid (EDTA).
• In biological research, it’s sometimes used as a stain for cellular structures due to its ability to bind with certain molecules and tissues, aiding in visualization under microscopes.
• It is utilized in various analytical procedures, including spectrophotometry and colorimetry.
• Due to its sensitivity to pH changes, it’s employed in water testing to determine the alkalinity of water samples.

Benefits :

• Versatile and stable
• Cost-effective and easy to use
• Highly sensitive to pH changes
