L-天冬氨酸 1-甲酯 - Introduction
H-Asp-OMe is a chemical that is also known as L-oxalyl gentisic acid 1-methyl ester. The following is a description of the nature, use, preparation and safety information of the substance:
Nature:
H-Asp-OMe is a colorless to slightly yellow oily liquid with a special ammonia smell. It is soluble in organic solvents such as ethanol and dimethyl sulfoxide, but insoluble in water.
Use:
H-Asp-OMe are mainly used as intermediates in pharmaceutical synthesis and organic synthesis. It can be used to prepare amino acid derivatives, such as oxalyl gentisic acid and cytidine from Agaricus. In addition, it can also be used in the synthesis of glutamic acid to relieve amines.
Method:
The preparation of H-Asp-OMe is generally carried out by treating L-aspartic acid with an N-protecting agent. The specific preparation process varies depending on the purpose and conditions of the study.
Safety Information:
H-Asp-OMe is a chemical substance, so the following safety precautions should be paid attention to when handling and using:
1. Avoid contact with skin and eyes. In case of accidental contact, immediately flush the affected area with plenty of water and seek medical help.
2. Avoid inhalation of its vapor. Operate in a well-ventilated area or wear appropriate protective equipment, such as a respirator.
3. Should be stored with oxidants, strong acid, alkali and other substances isolated, so as to avoid dangerous reaction.
4. When using and handling the substance, please refer to the relevant safety data form for detailed safety information and operating advice.
Because H-Asp-OMe are organic chemicals, use caution and follow laboratory safety procedures and guidelines.
