Description

(S)-2,4-Dihydroxybutyric Acid is a chiral, non-proteinogenic hydroxy acid with significant utility in organic synthesis and pharmaceutical research. Its stereochemistry and bifunctional nature make it a valuable chiral building block for the synthesis of complex molecules, including active pharmaceutical ingredients (APIs) and fine chemicals. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to incorporate specific stereocenters into their target compounds.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the synthesis of enantiomerically pure drugs, particularly those targeting metabolic pathways or requiring specific spatial orientation for biological activity.
• Biochemical Research: Used in the study of metabolic processes, enzyme mechanisms, and as a precursor for labeled compounds in tracer studies.
• Agrochemical Synthesis: Serves as a building block for developing chiral herbicides, fungicides, and plant growth regulators with enhanced efficacy and selectivity.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, flavors, fragrances, and advanced materials where optical purity is critical.
• Ligand and Catalyst Development: Utilized for constructing chiral ligands and organocatalysts used in asymmetric synthesis.

Quality Control

Our (S)-2,4-Dihydroxybutyric Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by HPLC, to ensure it meets the high standards required for advanced synthetic applications. A Certificate of Analysis (COA) detailing identity, purity, and chiral excess is provided with every shipment, ensuring full traceability and compliance with customer specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and performance.
