138505-15-4 - Introduction
2-(3,4-Dimethoxyphenyl)butanoic acid(2-(3,4-dimethoxyphenyl) butyric acid) is a chemical compound also known as DMB acid. The following is a description of its nature, use, formulation and safety information:
Nature:
-Appearance: DMB acid is a white crystalline solid.
-Solubility: It has good solubility in common solvents, such as ethanol and dimethylformamide.
-Melting point: The melting point of DMB acid is about 130-132°C.
Use:
- DMB acid is an organic acid that can be used as a reagent in organic synthesis.
-It is widely used in the pharmaceutical industry as an intermediate for synthetic drugs, antibiotics and other organic compounds.
Preparation Method:
- DMB acid can be synthesized by the following steps: First, 3,4-dimethoxybenzaldehyde is reacted with acetone under alkaline conditions to generate 3,4-dimethoxyphenylacetone. This intermediate is then subjected to a condensation reaction with formaldehyde to give 3,4-dimethoxyphenylpropanol. Finally, the final 2-(3,4-dimethoxyphenyl) butyric acid was obtained by oxidation of 3,4-dimethoxyphenyl propanol.
Safety Information:
- DMB acid is generally relatively safe under normal operating conditions. However, as with any chemical, proper laboratory practices and personal protective measures should be followed.
- DMB acid may cause irritation to the eyes and skin, so you should wear appropriate protective gloves and goggles during operation.
-If you accidentally come into contact with DMB acid, immediately rinse the affected area with plenty of water and seek medical attention if necessary.
