Description

Butyl 3-Hydroxybutyrate is a high-purity ester derivative of 3-hydroxybutyric acid, a key monomer of the biodegradable polymer polyhydroxybutyrate (PHB). This compound serves as a versatile chemical intermediate and a valuable reference standard in analytical and research settings. It is primarily utilized by manufacturers and researchers in the polymer, pharmaceutical, and specialty chemical industries for synthesis, quality control, and metabolic studies.

Application

• Polymer Research & Synthesis: As a monomeric analog and precursor for developing and modifying biodegradable polyhydroxyalkanoate (PHA) polymers.
• Pharmaceutical Intermediates: Used in the synthesis of more complex molecules for pharmaceutical applications, including prodrug development.
• Analytical Reference Standard: A critical standard for Gas Chromatography (GC) and High-Performance Liquid Chromatography (HPLC) methods to quantify ketone bodies (like β-hydroxybutyrate) in clinical, nutritional, and metabolic research.
• Flavor & Fragrance Industry: Employed as a building block for creating specific ester notes in advanced fragrance compositions and flavor agents.
• Biochemical Research: Used in studies of ketosis, metabolic pathways (especially fatty acid metabolism), and energy metabolism in nutritional science.
• Specialty Chemical Synthesis: Acts as a chiral synthon for the production of fine chemicals and other specialty esters with specific optical activity.
