Quality Control

Every batch of Difluoro-1,3-Butadiyne is produced and analyzed under strict quality protocols. We employ advanced analytical techniques including GC, GC-MS, NMR, and FTIR to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at recommended temperatures (typically 2-8°C or as specified on the label). Due to its hygroscopic and highly volatile nature, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and decomposition. Keep away from heat, sparks, and open flame.
