Quality Control

Our Di-Sodium Acetylide is produced and handled under stringent quality protocols to ensure batch-to-batch consistency and reliability for sensitive synthetic applications. Quality is verified through a suite of analytical techniques, including titration for active content and spectroscopic methods for identification. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality management systems.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly reactive and hygroscopic (moisture-sensitive) nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Keep away from heat, sparks, open flames, and incompatible materials such as strong acids, oxidizers, and water.
