Quality Control

Every batch of Pss-Chloropropyl-Heptaisobutyl Substitu& CAS NO 480438-84-4 is manufactured under controlled conditions and undergoes rigorous analytical testing to ensure identity, purity, and consistency. Our quality assurance protocol is designed to meet the stringent requirements of research and industrial applications. 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 place at 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 or argon) after opening to prevent degradation.
