Quality Control

Our high-purity reference materials are produced and handled under strict quality protocols. Each batch undergoes comprehensive analysis using advanced techniques like GC-MS, HPLC, and NMR to confirm identity and purity. We provide a detailed Certificate of Analysis (COA) with each shipment, documenting batch-specific results. Our quality system ensures traceability and compliance with relevant standards for analytical and research chemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). This compound is light-sensitive; prolonged exposure to light should be avoided to maintain stability and purity. Keep the container sealed in a dry environment to prevent moisture absorption.
