Quality Control

Our production of [(E)-1-Butenyloxy]Trimethylsilane adheres to stringent internal quality standards to ensure batch-to-batch consistency and high purity. Each lot is analyzed via GC, NMR, and FTIR to confirm identity, isomeric purity (E-configuration), and chemical composition. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Keep away from heat, sparks, and open flame.
