Quality Control

Every batch of 2-Dimethylamino-5-Phenyldiazenyl-Benzene-1,3-Disulfonic Acid is manufactured and tested under a strict quality management system. We ensure consistent purity and identity through a battery of analytical techniques including HPLC, NMR, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical characteristics is provided with each shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which may affect stability and handling properties.
