Quality Control

Every batch of our Bis(n-Propyltetramethylcyclopentadienyl)Strontium Dimethoxyethane Adduct is manufactured and tested under stringent inert atmosphere conditions to ensure optimal purity and performance. We adhere to rigorous analytical protocols, including NMR and elemental analysis, to guarantee consistency and meet the exacting standards of the semiconductor industry. A comprehensive Certificate of Analysis (COA) detailing purity, metal content, and solvent levels is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at temperatures between 2°C and 8°C (refrigerated) to maintain stability and prevent decomposition. This compound is moisture-sensitive (hygroscopic) and easily oxidized; therefore, it must be handled exclusively in a dry, oxygen-free environment using Schlenk line or glovebox techniques.
