Neutral red is a pH indicator that is commonly used in biological staining. It is a weak acid that exists in two forms: a protonated form (red) and a deprotonated form (yellow), depending on the pH of the environment. In acidic conditions, it appears red, while in neutral to alkaline conditions, it turns yellow. Additionally, neutral red can permeate cell membranes and accumulate in lysosomes, making it useful for assessing cell viability and function in various biological applications.
