Quality Control

Every batch of Q Et CAS NO 45732-65-8 is manufactured under a strict quality management system. We ensure high purity and batch-to-batch consistency through rigorous analytical testing, including HPLC, NMR, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee it meets your specific research or production requirements.

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 after opening to prevent degradation from atmospheric moisture.
