19703-92-5 - Introduction

5-Methyl-1,2, Acid, also known as MMT(Methylcyclopropene), is an organic compound. The following is a description of its nature, use, preparation and safety information:

Nature:
- MMT is a colorless liquid with a pungent odor.
-It has low solubility and is soluble in organic solvents such as ethanol and methanol.
- MMT is a stable compound, but it will decompose at high temperature and under sunlight.

Use:
- MMT is mainly used as a plant growth regulator, and its main function is to inhibit the ethylene synthesis of plants, thereby delaying the maturation and aging process of plants.
-due to its characteristics of delayed plant maturity, MMT has important application in the process of storage and transportation of fruits and vegetables.

Method:
The regular preparation method of-MMT is obtained by reacting Oxadiazole with methanol. Specific steps include heating the reaction mixture, distillation, and purification.

Safety Information:
- MMT is relatively safe to use under general conditions, but the following points still need to be paid attention:
-Avoid inhalation and skin contact due to its pungent odor. Appropriate use of personal protective equipment, such as gloves, masks, goggles, etc.
- MMT should be kept away from fire and high temperature to prevent its decomposition or combustion.
-When handling or storing MMT, relevant safety operating procedures and operating techniques should be followed to ensure personal safety and environmental protection. When necessary, it should be operated in a well-ventilated place.
