Quality Control

Our 6,7-Dihydro-5H-Benzocycloheptene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC/HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets the high standards required for advanced synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its sensitivity to strong oxidizers, store separately from oxidizing agents. The container must be kept tightly sealed to prevent contamination and moisture absorption.
