Quality Control

Our chiral building blocks are produced under 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, GC, NMR, and IR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing identity, purity (assay), enantiomeric excess (ee), and impurity profile is provided with every shipment to support your regulatory and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Due to its sensitivity, keep away from oxidizing agents and strong bases.
