Quality Control

Our (2S,3R)-2,3,4-Trihydroxybutanoic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity verification by HPLC, to ensure compliance with high-grade specifications. A comprehensive Certificate of Analysis (COA) detailing identity, assay, impurity profile, and stereochemical purity is provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which may affect stability and handling properties.
