Quality Control

Our Peg9-T-Butly Ester is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent moisture uptake and oxidation. Keep away from strong oxidizing agents.
