Description

2-Hydroxypentanedioic Acid is a versatile hydroxy dicarboxylic acid that serves as a valuable chiral building block and intermediate in organic synthesis. Its molecular structure, featuring both hydroxyl and carboxylic acid functional groups, makes it a critical precursor for the production of fine chemicals, pharmaceuticals, and specialty polymers. This compound is essential for research and manufacturing in the pharmaceutical, agrochemical, and flavor & fragrance industries, where precise molecular architecture is required.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in the development of antiviral and cardiovascular drugs.
• Fine Chemical Synthesis: Used as a building block for producing complex organic molecules, including chelating agents and specialty esters.
• Agrochemicals: Intermediate in the manufacture of herbicides, pesticides, and plant growth regulators that require specific stereochemistry.
• Flavor and Fragrance Industry: Serves as a precursor for lactones and other compounds that contribute to creamy, fruity, or nutty flavor profiles.
• Polymer Chemistry: Monomer or co-monomer for the synthesis of biodegradable polyesters and polyamides with tailored properties.
• Biochemical Research: Used in enzymatic studies and as a standard or reagent in metabolic pathway analysis.
• Cosmetic Ingredients: Intermediate for the production of skin-conditioning agents and emulsifiers.
