Quality Control

Our (S)-(-)-2-Methoxypropionic 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 synthetic applications. Certificates of Analysis (COA) with detailed chromatographic data (enantiomeric excess) and full specifications are provided with every shipment.

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). Due to its nature as a strong acid/organic solvent, keep away from incompatible materials such as strong bases, oxidizing agents, and reactive metals. The container must be kept tightly sealed to prevent absorption of moisture from the air.
