Quality Control

Every batch of 2-Bromo-3'-Methoxyacetophenone-13Cd3 is produced and tested under strict quality management protocols to ensure exceptional isotopic and chemical purity. Our standard analytical suite includes NMR (¹H, ¹³C), mass spectrometry, and HPLC to verify identity, isotopic enrichment (typically >99 atom % ¹³C and >98 atom % D), and chemical purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment.

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 (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
