Fast Yellow G

Description:

Fast Yellow G, with the CAS number 2512-29-0, is an organic compound primarily used as a dye in various applications, including textiles and inks. It belongs to the azo dye class, characterized by the presence of one or more azo groups (-N=N-), which contribute to its vibrant yellow color. Fast Yellow G is known for its good lightfastness and washfastness, making it suitable for use in products that require durability against fading. The compound is typically soluble in water, allowing for easy application in dyeing processes. However, like many azo dyes, it may raise environmental and health concerns due to potential degradation products that can be harmful. Safety data sheets recommend handling it with care, using appropriate personal protective equipment to minimize exposure. Overall, Fast Yellow G is valued in the dye industry for its bright coloration and stability, but its use is subject to regulatory scrutiny regarding safety and environmental impact.
