Quality Control

Our (R)-Ammoniummandelat is manufactured under strict quality management systems to ensure batch-to-batch consistency and high chemical purity. Each lot undergoes comprehensive analytical testing, including chiral purity verification by HPLC, to meet the stringent requirements of pharmaceutical and fine chemical applications. Certificates of Analysis (COA) documenting identity, assay, chiral purity, and impurity profiles are available for 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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product stability and performance.
