Quality Control

Our Methane-D3-Thiol is produced and handled under stringent quality protocols to ensure the highest isotopic and chemical purity for research applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as isotopic enrichment (D atom %), chemical purity by GC, and identity confirmation. We adhere to relevant industry standards for high-purity labeled compounds, and custom specifications for GMP or other regulatory frameworks can be discussed.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and gaseous nature under standard conditions, this product is typically supplied in a sealed gas cylinder or ampule and must be stored in a cool, well-ventilated area, away from heat sources and strong oxidizing agents. For long-term stability, storage at recommended low temperatures is advised. Handle and store under an inert atmosphere to prevent degradation.
