Quality Control

Our Benzenebutanoic Acid, α-Hydroxy-4-Methyl-, Methyl Ester, (αs)- is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity assessment by HPLC, to ensure it meets the high standards required for pharmaceutical and fine chemical applications. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, store in a cool, dry place, ideally at controlled room temperature (15-25°C). For long-term storage, consider using desiccants or storing under an inert atmosphere to maintain product integrity and prevent moisture uptake.
