Quality Control

Our Methylbenzene-13C7 is manufactured under strict quality systems to ensure exceptional isotopic and chemical purity. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment, chemical purity, and solvent residue profiles. We ensure compliance with the stringent requirements for research and analytical standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place away from heat sources and incompatible materials. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature: 2°C to 8°C for long-term stability.
