1,4-Bis(2-cyanostyryl)benzene CAS#13001-39-3

1,4-Bis(2-cyanostyryl)benzene (CAS 13001-39-3) is a fluorescent brightener and can also be considered a special type of dye.
It has conjugated double bonds and a well-planar structure. When exposed to ultraviolet light, it can absorb the energy of ultraviolet light and emit visible blue light or blue-violet fluorescence, thereby achieving whitening and brightening effects.
This compound is commonly used in many fields, such as textiles, papermaking, detergents, etc., to improve the appearance whiteness and gloss of products.
When using it, it is necessary to follow relevant regulations and standards to ensure safe and reasonable use. At the same time, it is also necessary to avoid its potential impact on the environment.
Some of its related properties are as follows:
Appearance: light yellow
Melting point: 230-234 ºC
Boiling point: 571.3 ºC at 760 mmHg
Flash point: 272.8 ºC
