Quality Control

Our Bis(N,n-Di-I-Propylformamidinato)Calcium(Ii) Dimer is manufactured under stringent conditions to meet the exacting standards of the electronics and advanced materials industries. Every batch undergoes rigorous analytical testing, including inductively coupled plasma mass spectrometry (ICP-MS) and nuclear magnetic resonance (NMR), to verify the 99.99% minimum calcium purity and ensure low levels of critical metallic impurities. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from incompatible materials such as strong acids and oxidizers.
