Quality Control

Our 4-Hydrazinobenzoic Acid-D4 Hydrochloride is manufactured under strict quality systems to ensure high isotopic purity and chemical integrity. Each batch is characterized by advanced analytical techniques including NMR, HPLC, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment, chemical purity, and identity is provided with every shipment to support your research and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C in a cool, dry place. This material is hygroscopic (moisture-sensitive) and easily oxidized; prolonged exposure to air and moisture should be avoided. For long-term storage, consider keeping the container under an inert atmosphere.
