Quality Control

Our 1,3-Benzene(Dicarboxylic Acid-13C2) is manufactured under strict quality protocols to ensure exceptional isotopic and chemical purity, critical for sensitive analytical applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing parameters such as isotopic enrichment (atom % 13C), chemical purity by HPLC, and identification by spectroscopic methods. We adhere to relevant industry standards for research chemicals.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under anhydrous conditions to prevent degradation and maintain isotopic integrity.
