Quality Control

Our Hydrazinecarboxylic Acid, 2-(5-Isoxazolylmethyl)-, 1,1-Dimethylethyl Ester (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via NMR and IR spectroscopy, to ensure it meets the high standards required for research and process development. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation from moisture and oxidation.
