66990-32-7 - Introduction
10,12-Pentacosadiynoic acid(10,12-Pentacosadiynoic acid) is an organic compound with the chemical formula C25H38O2. It is a solid, colorless to with yellowish crystals, with a chilli-like odor.
10,12-Pentacosadiynoic acid is primarily used in research and laboratory applications. It can be used as a light source material, a light emitting device and a component of a polymer light emitter. In view of its luminescent properties and unique structure, it has potential applications in the field of optics and luminescent materials. In addition, it can also be used in the synthesis of catalysts and catalytic reagents for organic chemical reactions.
The preparation method of 10,12-Pentacosadiynoic acid can be prepared by first synthesizing 10,12-25 carbon diacetylene alcohol and then oxidizing it. In general, cetylmagnesium bromide can be reacted with propionitrile to produce 10,12-25 carbon diacetynol. Then, it was oxidized under the condition of perchloric acid to obtain the target product 10,12-Pentacosadiynoic acid.
Regarding safety information, 10,12-Pentacosadiynoic acid has very low toxicity under normal use. However, proper laboratory safety procedures should be followed during handling and handling. Such compounds can cause irritation and may cause damage to the eyes, skin and respiratory system. Therefore, it is recommended to wear appropriate personal protective equipment, such as laboratory masks, gloves and protective glasses. When in use, should avoid inhalation, ingestion and skin contact. After treatment and disposal, attention should be paid to correct waste treatment methods.
