(4-METHYLPHENOXY)ACETIC ACID - Introduction
(4-Methylphenyl) acetic acid, chemical formula C9H10O3, is an organic compound, commonly abbreviated as MPA. The following is an introduction to the nature, use, preparation and safety information of (4-Methylphenyl) acetic acid:
Nature:
-Appearance:(4-Methylphenoxy)acetic acid is a white to pale yellow crystalline powder.
-Solubility: It can be dissolved in common organic solvents, such as ethanol, acetone and dichloromethane, but the solubility in water is low.
-Melting point: It has a melting point of about 54-56°C.
Use:
-Pesticide intermediates:(4-Methylphenoxy)acetic acid is widely used as an intermediate for pesticides and herbicides, such as the production of sulfate pesticides, such as 2,4-drops, and its esters are mainly obtained through esterification.
-Chemical synthesis: It can be used as a starting material or reaction intermediate for the synthesis of other organic compounds.
-Research:(4-Methylphenoxy)acetic acid is also used in laboratory research, such as copper-catalyzed reactions.
Method:
The preparation method of (4-Methylphenyl) acetic acid can be realized by the following steps:
-Under alkaline conditions, 4-methylphenol is prepared by Grignard reagent reaction (for example: 4-methylphenylmagnesium bromide reacts with carbon dioxide).
-4-Methylphenol is reacted with haloacetic acid to prepare (4-Methylphenol) acetic acid by esterification.
Safety Information:
- (4-Methylphenyl) acetic acid has low toxicity, but it still needs to be used and stored correctly.
-During operation, care should be taken to avoid contact with skin, eyes and respiratory tract. Use personal protective equipment, such as lab gloves, safety glasses and gas masks, to ensure safe handling.
-It is recommended to operate and store in a well-ventilated place, away from fire and heat sources.
-If swallowed or touched by accident, please consult a doctor immediately and bring the product's Material Safety Data Sheet (MSDS).
Note: The above information is for reference only. Please follow the relevant laboratory operation specifications and safety protection measures during specific operation and use.
