Quality Control

Our 3-Methyl-D3-Thiopropanal is produced under controlled conditions to ensure high isotopic and chemical purity, meeting the stringent requirements of research and analytical applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing key parameters such as isotopic purity (D-enrichment), chemical purity (by GC or NMR), and identity confirmation. We adhere to rigorous quality testing protocols to ensure batch-to-batch consistency and reliability for your critical work.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at room temperature (15-25°C). Due to its highly volatile and light-sensitive nature, prolonged exposure to air, heat, or light should be avoided to maintain stability and purity.
