3,3-bis(2-ethoxy-4-N,N-diethylaMinophenyl)-7(4)-azaphthalide CAS#132467-74-4

3,3-Bis(2-ethoxy-4-N,N-diethylaminophenyl)-7(4)-azabenzofuran (CAS: 132467-74-4) is an organic compound.
It can be used as a dye or pigment. For example, in reversible temperature-sensitive color-changing neutral ink, this type of colorless dye can be used as an electron-donating compound. The basic principle is that in a phase change agent with a certain phase change temperature, the colorless dye acts as an electron-donating compound and transfers electrons with the color developer (electron-accepting compound), thereby achieving the purpose of color development and color elimination, and then achieving the color change effect at a specific temperature, which can be used for writing and modification, etc.
In some specific applications, it is often used in combination with bisphenol color developers (such as bisphenol A, bisphenol C, etc.) and specific phase change agents (such as long-chain alcohols, esters, ketones, amides, etc.) to form materials with temperature-sensitive color-changing properties.
It may also be a synthetic intermediate for some functional materials, used in the research and development and production of related chemical products.
