76801-85-9 - Introduction

 

Azithromycin A, also known as Azelaic acid, is a colorless crystalline powder containing seven carbon atoms. The following is an introduction to the properties, uses, preparation and safety information of azithromycin A:

 

Nature:

 

- It can be dissolved in organic solvents such as water, ethanol and ether.

 

- Azithromycin A has the characteristics of polyacid, with a certain acidity.

 

Purpose:

 

- It has the effect of inhibiting bacterial growth, especially for the acne-causing propionibacterium and other bacteria have a certain bactericidal effect.

 

Azithromycin A can also be used in industrial fields such as dye and polymer synthesis.

 

Preparation:

 

- Azithromycin A is generally prepared by a process of air oxidation or reduction. In the preparation process, lower concentrations of oxidants or reducing agents, such as excess ozone or nitrile solvents, can be used.

 

Safety information:

 

- However, in the course of use, it may cause some skin irritation, such as stinging, itching, redness, etc., and it is necessary to follow the appropriate use and storage methods, and avoid contact with the eyes and mucous membranes.

 

- For people who are allergic to azithromycin A, it is necessary to avoid using this substance.
