Fluorescent brightener OP - Introduction
o-Cyanostilbene is an organic compound with the chemical formula C16H11N. It is a diene compound with an ortho substituent on the benzene ring with a cyano (-CN) functional group.
O-cyanostilbene is a yellow crystal, soluble in organic solvents such as ethanol and ether. It has good thermal and light stability, and is an important fluorescent chromophore, which can be used in the field of chemiluminescence materials, optical sensors and so on.
o-cyanostilbene can be prepared by cyanation reaction of aromatic carboxylic acid. First, under alkaline conditions, aromatic carboxylic acid reacts with nitrite to form aromatic nitrite, and then reacts with metal cyanide to form stilbene with a cyano group in the ortho position.
in the use of o-cyanostilbene need to pay attention to some safety matters. O-cyanostilbene may cause irritation to the eyes, skin and respiratory system. The workplace should be well ventilated. Wear appropriate protective equipment, such as gloves, goggles, and respiratory protectors during use. In addition, o-cyanostilbene has a certain carcinogenic risk, so it is necessary to avoid prolonged contact and inhalation. In case of skin contact or inhalation, proper treatment and medical attention should be taken immediately. During storage and use, keep away from heat sources such as high temperature and open flames to avoid fire or explosion.
