Quality Control

Our L-Leucine 4-Methoxy-B-Naphthylamide*Free Base is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral purity verification, and identity confirmation (IR, NMR) to ensure it meets exacting research and development standards. Certificates of Analysis (COA) detailing all specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is light-sensitive (store away from light) and hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere if long-term storage is required.
