Quality Control

Our α-Zearalenol-D4 (Major) is manufactured under strict quality protocols to guarantee isotopic purity and chemical integrity for critical analytical applications. Each batch is characterized by advanced spectroscopic techniques, including NMR and High-Resolution Mass Spectrometry (HRMS), to confirm structure and deuterium incorporation. A comprehensive Certificate of Analysis (COA) detailing purity (by HPLC), isotopic enrichment, and other critical parameters is provided to ensure traceability and compliance with GLP and ISO 17025 standards.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a desiccated environment. This compound is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability. Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation.
