Quality Control

We maintain stringent quality control protocols for our chiral intermediates. Production follows current Good Manufacturing Practice (cGMP) principles where applicable, ensuring batch-to-batch consistency and traceability. Quality is verified through advanced analytical techniques including chiral HPLC, GC, and NMR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, enantiomeric excess, and impurity profiles 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 (typically 15-25°C). Keep away from heat, sparks, and open flame. For long-term storage, consider under an inert atmosphere to maintain optimal purity.
