Quality Control

Every batch of Disodium 2-[9-Chloro-3-(Sulphonatooxy)Naphtho[1,2-B]Thien-2-Yl]-1H-Indol-3-Yl Sulphate is manufactured and tested under a strict quality management system. We provide comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles to ensure it meets the exacting requirements for research and industrial synthesis. Our quality protocols are designed to support compliance with ISO and cGMP standards where applicable, guaranteeing traceability and batch-to-batch consistency for our global B2B clients.

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 light-sensitive (store away from light) and hygroscopic (moisture-sensitive); therefore, containers must be kept sealed to minimize exposure to atmospheric moisture.
