Quality Control

Every batch of 3H-Benz[E]Indole-3-Butanesulfonic Acid, Sodium Salt is manufactured under a strict quality management system. Our products undergo rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency meet the high standards required for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment. We adhere to cGMP principles where applicable to support our clients in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed after opening to minimize exposure to atmospheric moisture and light. Keep away from incompatible materials.
