Quality Control

Our 6-Heptyne-2,5-Diamine is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay (by HPLC or titration), impurity profile, and physical characteristics is provided with every shipment to guarantee it meets your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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 and moisture absorption.
