1918-78-1 - Introduction
ACID, also known as ACID, is an organic compound with the molecular formula C7H7NOS.
Nature: ACID is a solid with a special smell. It is soluble in organic solvents at room temperature, such as methanol, ethanol, acetone, etc. It is relatively stable in the air, but organic matter is generally easy to oxidize, so care should be taken to prevent contact with air during storage and use.
use: ACID is widely used in the field of organic synthesis. It is an important intermediate compound, which can be used to synthesize various organic functional compounds, such as drugs, dyes, complexing agents and so on. In addition, it can also be used as a functional modifier of cation exchange resins for water treatment, ion exchange, separation and purification.
Preparation method: A common preparation method is to obtain ACID by the reaction of 3-thiophenecarbonyl chloride and methyl lithium. For specific synthetic steps, reference may be made to relevant documents such as Handbook of Organic Synthetic Chemistry.
Safety information: avoid contact with skin and eyes to prevent inhalation and ingestion. When operating, wear appropriate personal protective equipment, such as gloves, goggles and protective clothing, and ensure that the operation is carried out in a well-ventilated place. When stored, keep away from ignition and oxidizing agents. When handling this compound, please refer to the Material Safety Data Sheet (MSDS) and the relevant safety manual, and strictly follow the safety procedures.
