Quality Control

Our 1H-Imidazole, 4,5-Diethynyl-1-Methyl- (9Ci) is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity for research and development applications. All products undergo rigorous analytical testing, including HPLC, NMR, and GC-MS, to verify identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its sensitivity to light and propensity for oxidation, prolonged exposure to air and light should be avoided.
