Quality Control

Every batch of 1,2-Cyclopropanedicarboxylic Acid, Dihydrazide, (1R-Trans)- (9Ci) is produced under strict quality management protocols. Our products undergo rigorous analytical testing to ensure compliance with exacting purity and chiral integrity standards required for advanced synthetic applications. A comprehensive Certificate of Analysis (COA), detailing identity, purity, enantiomeric excess, and impurity profiles, is provided with each shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; therefore, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to maintain product integrity and prevent degradation.
