Quality Control

Our high-purity chiral intermediates are manufactured under strict quality management systems. Each batch is characterized and tested to ensure identity, purity, and enantiomeric excess (e.e.) meet stringent specifications. Comprehensive analytical methods including HPLC, GC, Chiral HPLC, and NMR are employed. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment to ensure traceability and batch-to-batch consistency for your critical R&D and cGMP manufacturing processes.

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). Keep the container tightly sealed when not in use to protect from moisture.
