Quality Control

Our L-Isoleucine, n-[n-[n-[(4-Methylphenylsulfonyl]-S-(Phenylmethyl)-L-Cysteinyl]-L-Tyrosyl]-, Hydrazide (9Ci) is manufactured under controlled conditions to ensure the highest standards of purity and identity. Each batch undergoes rigorous analytical testing, including HPLC for purity and spectroscopic identification (NMR, MS). A comprehensive Certificate of Analysis (COA) detailing all test results is provided to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
