Quality Control

Our 2,6-Diethynylnaphthalene is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including HPLC, GC, and NMR, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. For long-term storage, keep the container under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 2-8°C. This compound is easily oxidized and light-sensitive. Allow the sealed container to equilibrate to room temperature before opening to prevent moisture condensation.
