108998-83-0 - Introduction

(S)-Triphenylethylene glycol is an organic compound with the chemical formula C20H18O2. It is a white solid with a melting point of 82-85°C and a boiling point of 380°C at room temperature. It has good solubility and is soluble in many organic solvents, such as chloroform, ether and dimethylformamide.

(S)-triphenyl ethylene glycol is widely used in organic synthesis. It can be used as a catalyst and ligand to participate in metal-catalyzed reactions, such as reacting with metal salts to form corresponding complexes. It can also be used as a raw material for fluorescent substances and photosensitive substances, and is widely used in organic synthesis reduction, esterification, electrophilic substitution and other reactions.

The common method for preparing (S)-triphenylethylene glycol is obtained by the hydrogen reduction reaction of phenylacetylene and benzaldehyde. The specific process is the reaction of phenylacetylene and benzaldehyde with a suitable catalyst under suitable reaction conditions to produce (S)-triphenylethylene glycol.

When using and handling (S)-triphenylethylene glycol, you need to pay attention to its safety information. It is an organic compound that is potentially dangerous. Inhalation of its vapors and contact with skin and eyes should be avoided. Personal protective equipment such as chemical protective gloves and goggles should be worn during operation. At the same time, during storage and handling, it should be kept away from fire and high temperature environment. In the event of an accidental leak, appropriate clean-up measures should be taken immediately and to ensure that gas or liquid does not enter the sewer or come into contact with combustibles.
