CAS 13001-40-6

Fluorescent brightener 199

Description:

Fluorescent brightener 199, also known by its CAS number 13001-40-6, is a synthetic organic compound commonly used as a fluorescent whitening agent. It belongs to the class of stilbene derivatives and is characterized by its ability to absorb ultraviolet light and re-emit it as visible blue light, enhancing the brightness and whiteness of materials. This compound is widely utilized in various applications, including textiles, paper, and detergents, to improve the appearance of fabrics and surfaces by counteracting yellowing. Fluorescent brightener 199 is typically soluble in organic solvents and exhibits good stability under normal conditions, although its performance can be affected by factors such as pH and temperature. Safety data indicates that while it is generally considered to have low toxicity, appropriate handling and safety measures should be observed to minimize exposure. Overall, its effectiveness in enhancing brightness makes it a valuable additive in many industrial and consumer products.
