Key Properties
Quinaldine red indicator solution is a ready-made preparation of the dye quinaldine red, designed for direct titration use in laboratory settings. This solution is particularly useful in acid-base titrations, where it serves as a pH indicator, changing color in response to pH variations. Quinaldine red is a synthetic dye that exhibits distinct color changes, making it an effective tool for determining the endpoint of titrations. The solution is prepared to a specific concentration, ensuring consistent performance in analytical applications.
Also known as Quinaldine Red, 2-(1-Quinolyl)-1H-pyrrole.
