Quality Control

Our Acetophenone-Methyl-13C is produced under stringent conditions to ensure high isotopic and chemical purity, critical for sensitive analytical applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically ≥99 atom % 13C), chemical purity (by GC or HPLC), and identity confirmation. We adhere to rigorous quality testing protocols to guarantee batch-to-batch consistency and reliability for your research needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place at room temperature (15-25°C). Keep away from heat, sparks, and open flame.
