1-Methyl-1H-pyrrole-2-carbonyl chloride - Introduction
It is an organic compound whose structural formula is C6H6ClNO. The following is a description of its nature, use, formulation and safety information:
Nature:
chloride is a colorless to yellowish liquid that has a pungent odor at room temperature. It is highly corrosive and can react violently with water, acids and alkalis. It is susceptible to moisture and decomposition in the air.
Use: chloride is widely used as a substituent in organic synthesis or as an intermediate for the construction of other organic molecular skeletons. It can be used to synthesize a variety of organic compounds, such as drugs, dyes and pesticides. In addition, it can also be used as a reagent for chemical research.
Method:
The preparation method of chloride is mainly realized by the following steps:
1. First dissolve 1-methyl pyrrole in anhydrous dichloromethane;
2. Add excess homogenate anhydrous hydrochloric acid to continue the reaction;
3. The reaction mixture was cooled and then filtered;
4. Distillate the filtered solution to collect the prepared chlorine.
Safety Information:
. chloride is irritating and corrosive, and may cause burns or injuries in contact with skin and eyes. Appropriate protective equipment such as safety glasses, gloves and laboratory coats should be worn during handling. Operate in a well-ventilated area to prevent gas accumulation. Avoid contact with acids, alkalis and oxidants. If exposed or inhaled, seek medical help immediately.
