- 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
