Quality Control

Our Dl-Phenylalanine-15N is produced under strict quality management systems to ensure the highest isotopic and chemical purity for research applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing parameters such as isotopic enrichment (Atom % 15N), chemical purity (by HPLC), and chiral purity. We support compliance with relevant research standards and specifications can be tailored to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container should be kept in a desiccated environment to prevent moisture absorption, which can affect stability and handling.
