Quality Control

Our Aminopropyllsobutyl Poss is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot is characterized using advanced analytical techniques including NMR, FT-IR, and HPLC. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and physical properties is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation.
