• Application: Azocal is a versatile organic sulfonated monoazo dye primarily used for dyeing wool, silk, and leather, as well as serving as a pigment. This dye is known for its distinctive color changes under various chemical conditions, appearing blue light red in its original form, orange when dissolved in water, and displaying a range of colors when mixed with different substances. For example, it turns yellow-red in concentrated sulfuric acid and orange in nitric acid or sodium hydroxide solutions. Azocal demonstrates varied fastness properties, providing strength in ironing and water fastness, and maintaining moderate to good resistance to light, perspiration, and soaping. Its performance conforms to international standards such as ISO and AATCC, making it a reliable choice for applications requiring consistent color stability.
