fenolftaleinilla

Fenolftaleinilla, also known as Phenolphthaleinilla, is a chemical compound that belongs to the class of phenolphthalein derivatives. It is characterized by its chemical formula C20H14O4 and a molecular weight of 318.32 g/mol. The compound is a white to off-white crystalline powder that is soluble in ethanol and dimethyl sulfoxide, but insoluble in water.

Fenolftaleinilla is primarily used as a pH indicator in chemical and biological research. It exhibits a color change from colorless to pink in the pH range of 8.2 to 10.0, making it useful for titrations and pH measurements. Its sensitivity to pH changes allows for precise determination of endpoint in various chemical reactions.

The synthesis of Fenolftaleinilla typically involves the condensation of phthalic anhydride with two equivalents of o-cresol, followed by the addition of sodium hydroxide to form the sodium salt. This compound is often used in laboratory settings due to its stability and reliability as a pH indicator.

In terms of safety, Fenolftaleinilla should be handled with care. It is considered a skin and eye irritant, and inhalation of its dust should be avoided. Proper personal protective equipment, including gloves and safety glasses, should be worn when handling the compound. Additionally, it is important to dispose of Fenolftaleinilla waste according to local regulations to minimize environmental impact.
