CAS 33869-21-5: lacmoid

Description: Lacmoid, with the CAS number 33869-21-5, is a chemical compound primarily used as a pH indicator in various applications, particularly in analytical chemistry and biological research. It is known for its ability to change color in response to different pH levels, typically transitioning from yellow in acidic conditions to blue in alkaline environments. This property makes lacmoid valuable for visualizing pH changes in solutions. The compound is a synthetic dye derived from the oxidation of certain organic compounds and is often utilized in titrations and other laboratory procedures where pH monitoring is essential. Lacmoid is generally considered to be stable under normal conditions, but like many dyes, it may be sensitive to light and heat, which can affect its performance. Safety data sheets should be consulted for handling and disposal guidelines, as with any chemical substance. Overall, lacmoid serves as an important tool in both educational and professional settings for pH determination.
