Quality Control

This analytical standard is produced under strict quality-controlled conditions to ensure isotopic purity and concentration accuracy. Each batch is characterized using advanced spectroscopic and chromatographic techniques, including NMR and HPLC-MS. A comprehensive Certificate of Analysis (COA) is provided, detailing the exact concentration, isotopic enrichment (99% 13C4), purity, solvent verification, and batch-specific data. Our quality system is designed to support GLP/GMP-compliant research and regulatory submissions.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below upon receipt for long-term stability. The solution is provided in methyl tert-butyl ether (MTBE), which is highly volatile and flammable; ensure adequate ventilation and follow all appropriate safety protocols for handling organic solvents. Allow the vial to equilibrate to room temperature before opening.
