6-Ketoenanthic acid - Introduction
5-Acetylvaleric acid(5-Acetylvaleric acid) is an organic compound with the chemical formula C7H12O3. The following is a description of its nature, use, preparation and safety information:
Nature:
- 5-Acetylvaleric acid is a colorless to yellowish liquid with a fruit and spice-like odor.
-it has a low vapor pressure at room temperature, soluble in alcohols, ethers and organic solvents, insoluble in water.
-It is a carboxylic acid that can react with a base to form the corresponding salt.
Use:
- 5-Acetylvaleric acid is commonly used in foods, spices and flavors to increase the aroma of foods or products.
-It can also be used to synthesize other organic compounds, such as drug intermediates, dyes and fragrance precursors.
Method:
- 5-Acetylvaleric acid can be prepared by esterification of valeric acid. Specifically, valeric acid can be reacted with acetic anhydride, using acetic acid as a catalyst, and subjected to a dehydration reaction at an appropriate temperature to produce 5-Acetylvaleric acid.
Safety Information:
-Specific toxicity of 5-Acetylvaleric acid has not been reported. However, as a chemical substance, it should be used with appropriate safe operating procedures.
-Direct contact with it may cause irritation to the skin and eyes, so you should drop less contact with the skin and eyes during use.
-Wear appropriate protective equipment such as gloves, goggles and lab coats during use to avoid inhaling aerosols.
-Before using 5-Acetylvaleric acid, read and follow its relevant safety data sheet (SDS).
