Quality Control

Every batch of o-Isobutyls-(2-(Diethylamino)Ethyl)Methylphosphonothioate is produced and tested under strict quality management protocols to ensure consistency and purity for research and industrial use. Our products undergo rigorous quality testing, including chromatographic and spectroscopic analysis, to ensure compliance with exacting standards. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is available upon request 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 place at a controlled room temperature (typically 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. Keep away from heat, sparks, and open flame.
