Permanent Orange (CAS 3468-63-1)

Permanent Orange, identified by its CAS number 3468-63-1, is a synthetic pigment known for its bright orange hue and robust stability, making it a popular choice in various industrial applications. This pigment falls within the category of azo compounds, which are characterized by their vivid colors and ability to form stable, insoluble particles suitable for use in paints, plastics, and textiles. The principal mechanism of action of Permanent Orange involves the formation of a complex molecular structure with azo bonds (-N=N-) that confer intense color and high resistance to fading when exposed to light and chemicals. In research contexts, Permanent Orange is often used to study pigment interactions with different media and the effects of environmental conditions on pigment stability. Scientists examine how this pigment adheres to different substrates, its resistance to solvents, and its thermal stability, which are critical parameters in developing durable materials and coatings. Additionally, its role in color fastness studies is significant, particularly in assessing how pigments can maintain their integrity and color in harsh conditions, including prolonged sun exposure and chemical exposure. These studies help in optimizing formulations that require long-lasting color retention, crucial for automotive, architectural, and fashion industries aiming to enhance product lifespan and aesthetic appeal.
