Quality Control

Our Boc-Thr(Bzl)-Osu is manufactured under strict quality management systems to ensure batch-to-batch consistency and high chemical purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis to confirm stereochemical integrity, and NMR for structural confirmation. Certificates of Analysis (COA) detailing all specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a freezer at -20°C or below. This product is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability and purity. Allow the sealed container to equilibrate to room temperature before opening to prevent moisture condensation.
