P-METHOXYPHENYL ISOTHIOCYANATE - Introduction
It is an organic compound with the chemical formula C8H7NOS. The following is a description of its nature, use, formulation and safety information:
Nature:
It is a colorless to yellow crystalline solid with a special thioether taste. It has a density of 1.17g/cm³ and a melting point of 60-62°C. This compound is soluble in organic solvents such as benzene, dichloromethane and ethanol, and insoluble in water.
Use:
It is mainly used for intermediates and raw materials in organic synthesis. It can be used as an intermediate for agricultural chemicals such as insecticides, fungicides, and plant growth regulators. In addition, the compound can also be applied to the synthesis of dyes, photoinitiators, etc.
Method:
can be synthesized by the reaction of p-cresol and isothiocyanic acid. The specific preparation method is as follows: first, P-cresol and sodium carbonate react to form p-cresol sodium, and then react with isothiocyanic acid to produce. After completion of the reaction, the target product can be obtained by crystallization or extraction.
Safety Information:
Low toxicity, but still need to pay attention to safe use. It may be irritating to the eyes, skin and respiratory system, so wear appropriate personal protective equipment such as protective gloves, goggles and masks. At the same time, avoid contact with oxidants, strong acids and other substances to avoid dangerous reactions. During storage and transportation, it should be kept in a dry, well-ventilated place, away from fire sources and open flames.
