Quality Control

Our (S)-(+)-2-Oxo-4-Phenyl-3-Oxazolidineacetic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity verification by HPLC, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) detailing purity, enantiomeric excess, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). This material may be hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of moisture from the air.
