Pigment Red 81

Description:
Pigment Red 81, with the CAS number 12224-98-5, 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 is classified as a monoazo pigment, which means it is derived from the reaction of an aromatic amine with a diazo compound. This pigment exhibits good thermal stability and resistance to solvents, making it suitable for outdoor applications where durability is essential. Additionally, Pigment Red 81 is known for its high tinting strength, allowing for effective coloration with relatively small amounts of pigment. It is often favored in formulations that require a bright, opaque red color. However, like many synthetic pigments, it is important to consider safety and environmental regulations when using Pigment Red 81, as some azo compounds can be subject to scrutiny regarding their potential breakdown products. Overall, its combination of color properties and stability makes it a popular choice in various industrial applications.

    Pigment red 81

    CAS:
    Pigment Red 81 is a fluorescent dye that belongs to the class of rhodamine dyes. Pigment Red 81 exhibits a strong fluorescence in the visible spectrum. It has been used as a matrix effect indicator and as a fluorescence probe for biological samples, such as lipids and proteins. Pigment Red 81 has also been used as an optical sensor for detecting enzyme activities, such as reactions involving nitrogen atoms or dextran sulfate, and it can be enhanced by using pluronic p123. The detection sensitivity of Pigment Red 81 is low, making it difficult to detect at lower concentrations.
