Quality Control

Our production of this chiral intermediate adheres to strict quality management protocols to ensure batch-to-batch consistency and high enantiomeric purity. Each lot is characterized using advanced analytical techniques including chiral HPLC, NMR, and GC-MS. A comprehensive Certificate of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profile is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which may affect stability and performance.
