Pigment Red 49:2

Description:

Pigment Red 49:2, with the CAS number 1103-39-5, is an organic pigment primarily used in various applications such as coatings, plastics, and inks due to its vibrant red hue and excellent lightfastness. It belongs to the class of azo pigments, characterized by the presence of an azo group (-N=N-) in its molecular structure, which contributes to its color properties. This pigment exhibits good thermal stability and resistance to solvents, making it suitable for use in demanding environments. Additionally, Pigment Red 49:2 is known for its high tinting strength, allowing for effective coloration even at low concentrations. It is often favored in formulations where durability and color retention are critical. However, as with many azo compounds, there are considerations regarding safety and environmental impact, necessitating adherence to regulatory guidelines during its use and disposal. Overall, Pigment Red 49:2 is valued for its performance in various industrial applications while requiring careful handling to mitigate any potential risks.
