Quality Control

Our n-Heptanephosphonic Dichloride is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, NMR, and titration methods, to ensure high chemical purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are 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, well-ventilated area at 15-25°C. Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation. Keep away from moisture, bases, and oxidizing agents.
