139232-40-9 - Introduction
5-Hydroxy-4,6,7-trimethyl-(2,3-dihydrobenzofuran)-2-acetic acid, also known as AHBA(5-Hydroxy-4,6,7-trimethyl-(2,3-dihydrobenzofuran)-2-acetic acid), is an organic compound.
Nature:
AHBA is a white crystalline solid with a sour, aromatic odor. It is sparingly soluble in water and can be dissolved in organic solvents such as ethanol or chloroform.
Use:
AHBA is commonly used as an intermediate in drug synthesis, particularly in the manufacture of aspirin and other non-steroidal anti-inflammatory drugs. As an important synthetic basic raw material, it has a wide range of applications in the pharmaceutical industry.
Preparation Method:
There are many ways to prepare AHBA, one of the common methods is obtained through the oxidation reaction of p-toluenesulfonic acid. This process may include the oxidation of p-toluenesulfonic acid, followed by acid-base neutralization, resulting in AHBA.
Safety Information:
AHBA is generally considered to be relatively safe under normal conditions of use. However, when handling it, it is still necessary to take appropriate laboratory safety measures to prevent direct contact with the skin or inhalation of gas. At the same time, appropriate waste disposal rules should be followed to ensure the safety of the environment and the human body. When using AHBA, keep it away from ignition and oxidant.
