Quality Control

Every batch of 3-Thiophenecarboxylicacid,4-Mercapto-(9Ci) is produced and tested under strict quality management protocols to ensure consistency and purity for research and industrial use. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as purity (by HPLC), identity confirmation, and impurity profiles. Our quality systems are designed to support cGMP and ISO standards for traceability and documentation.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Due to its sensitivity to oxidation and light, prolonged exposure to air or light should be avoided to maintain product integrity.
