Product Description:
Used as a pH indicator in analytical chemistry, particularly in titrations where a visible color change is needed in the alkaline range. It turns colorless in acidic solutions and blue to violet in basic solutions, making it useful for detecting the endpoint in alkaline titrations. Also employed in educational labs for demonstrating acid-base reactions due to its clear and distinct color transition. Its application extends to some biological staining techniques where pH sensitivity is required.
