What is Phenolphthalein (Biochemistry Grade)? Phenolphthalein, a high-purity reagent with the formula (C₂₀H₁₄O₄), is an essential compound widely used in acid-base titrations, quality control testing, and industrial processes that require precise pH monitoring. Known for its distinct phenolphthalein colour change, this versatile phenolphthalein indicator transitions from colourless in acidic solutions to pink in basic solutions, ensuring accurate and reliable results. Supplied as a white or slightly yellow crystalline powder, it adheres to strict quality standards, making it a staple in analytical and research applications.
Biochemistry Grade: This product is of the highest purity, ensuring consistent and reliable performance, particularly in biochemistry.
