Quality Control

Our n-Acetylmethionine Sulfoxide is manufactured under a quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. While specific grades can be produced, typical quality control includes assessment by HPLC, NMR, and specific rotation. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
