Quality Control

Our 2-Thiophenesulfinicacid, Sodium Salt (1:1) is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment and are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent oxidation and moisture absorption.
