Quality Control

This analytical standard is manufactured under strict quality-controlled conditions to guarantee isotopic enrichment and chemical purity. Each batch is verified for concentration accuracy and solution stability. A comprehensive Certificate of Analysis (COA) is provided, detailing results from NMR, HPLC, and GC-MS analyses to confirm the 99% isotopic purity and the absence of interfering impurities.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated). The solution is provided in toluene, which is flammable; keep away from heat, sparks, and open flame. For long-term stability, store in the original vial under an inert atmosphere if possible.
