Quality Control

Our (2R,3R)-2-[(D-Phe-L-Cys-L-Phe-D-Trp-L-Lys-L-Thr-L-Cys-)Amino]-1,3-Butanediol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, mass spectrometry (MS) for identity confirmation, and residual solvent analysis, to ensure it meets stringent specifications for research and development use. Certificates of Analysis (COA) with detailed chromatographic data are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a freezer. Due to its hygroscopic (moisture-sensitive) nature, the container must be sealed under an inert atmosphere (e.g., nitrogen or argon) after each use to prevent degradation. Allow the sealed vial to equilibrate to room temperature before opening to minimize moisture condensation.
