Quality Control

Our Sodium Isovalerate-1-13C is produced under strict quality management systems. Each batch is characterized to ensure high chemical purity and isotopic enrichment, typically exceeding 99% chemical purity and 99 atom % 13C. Certificates of Analysis (COA) are provided, detailing results for assay, isotopic purity, identity (IR, NMR), and specific tests for residual solvents and moisture. We support compliance with relevant research and development standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption.
