Phenolphthalein
Phenolphthalein (C20H14O4) is an organic compound used as an acid-base indicator. It is prepared using alcohol as a solvent due to its poor solubility in water. The indicator has a visual transition interval that is colorless at pH 8.0, pink at 8.5 and red at pH 10.0.
Key Features:
- Organic compound
- Used as an acid-base indicator
- Colorless at pH 8.0, pink at pH 8.5, and red at pH 10.0
- Poorly soluble in water, typically prepared using alcohol as a solvent
Product Specifications:
| CAS No. | 7220-79-3 |
| Formula | C16H18ClN3S . 3H2O |
| Application | For use in histology, bacteriology (staining), compounding of blood stains, anti-fungus treatment on fish eggs. It can also be used as a protozoacide and a fungicide. |
Perfect for: laboratories, educational institutions, and research facilities.
