Quality Control

We maintain stringent quality control protocols for our chiral intermediates. Production follows current Good Manufacturing Practices (cGMP) where applicable, and each batch is analyzed to confirm identity, purity, and enantiomeric excess (e.e.). A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing specifications such as assay (by HPLC or GC), chiral purity, and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). This compound is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and moisture uptake. Keep away from heat, sparks, and open flame.
