183741-91-5 - Introduction

acid is an organic compound whose properties are as follows:

Nature:
-Appearance: Colorless to pale yellow crystalline solid
-Melting point: About 210 ℃
-Solubility: Soluble in water and some organic solvents, such as ethanol and dimethyl sulfoxide

Use:
-acid is often used as an intermediate in organic synthesis and can be used to synthesize other compounds or drugs
-It can also be used as a ligand for metal ions, used for coordination chemical reactions and catalytic reactions

Method:
-the acid is usually made by the following steps:
1. Methoxylation of pyridine by methanol to obtain 2-methoxypyridine
2. React 2-methoxypyridine with bromomethanesulfonic acid to obtain 2-methoxypyridine -4-methanesulfonic acid
3. Reacting 2-methoxypyridine-4-methanesulfonic acid with ammonia to obtain 5-amino-2-methoxypyridine-4-methanesulfonic acid
4. Finally, neutralize the reaction with an alkaline solution to obtain acid.

Safety Information:
-the acid is generally safer under normal conditions of use.
-As an organic compound, it may be irritating to the skin, eyes and respiratory tract.
-Wear appropriate protective equipment such as gloves, goggles and masks during use.
-Avoid contact with oxidants and strong acids during storage and handling.
-If taken by mistake or inhaled by mistake, seek medical attention immediately. In case of skin or eye contact, rinse with plenty of water and seek medical attention if necessary.
