Quality Control

Every batch of 2-Chloro-5-Iodo-4-Pyridinol is manufactured under a strict quality management system. Our products undergo rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications and test results is provided with each shipment to guarantee compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and away from direct light sources to maintain stability and purity.
