Quality Control

Our Losindole (CAS 69175-77-5) is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and identity confirmation by spectroscopic methods (IR, NMR). We provide Certificates of Analysis (COA) with every shipment, detailing all critical quality parameters to ensure it meets the stringent requirements of research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 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.
