4-(Trifluoromethoxy)phenyl isothiocyanate - Introduction

Trifluoromethoxyphenyl isothiocyanate is an organic compound with a chemical formula of C9H4F3NOS and a molecular weight of 237.2g/mol. It is a colorless to pale yellow solid, soluble in organic solvents such as methylene chloride and anhydrous ethanol.

The compound can be used as a reagent in organic synthesis, and is often used to synthesize compounds with isothiocyanate groups. It can react as a substrate with other compounds to produce products with different properties. Due to the introduction of the trifluoromethoxy group, it has higher activity and special reactivity.

The method for preparing trifluoromethoxyphenyl isothiocyanate is usually obtained by reacting trifluoromethanol with phenyl isothiocyanate. First, phenyl isothiocyanate was dissolved in methylene chloride, then trifluoromethyl alcohol was added, and after the reaction, the product was precipitated from the solvent.

Regarding safety information, trifluoromethoxyphenyl isothiocyanate is generally relatively safe under normal operating conditions. However, since it is a chemical substance, it is still necessary to comply with safety regulations for handling and storage. Wear appropriate personal protective equipment to avoid contact with skin, eyes and respiratory tract. In addition, it should be stored in a dry, well-ventilated place, away from ignition and flammable substances.

It should be noted that the information provided above is for reference only. In actual use, the operation should be carried out according to the specific situation, and refer to the relevant safety data sheet and laboratory operation regulations.
