Quality Control

Our production of 3-(2,2-Dichlorocyclopropyl)-1,1,1,5,5,5-Hexamethyl-3-(Trimethylsiloxy)Pentanetrisiloxane adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including NMR, FT-IR, and GC/HPLC analysis, to ensure high purity and structural integrity. Certificates of Analysis (COA) detailing batch-specific results are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. 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. Recommended storage temperature is 2-8°C for long-term stability.
