Quality Control

Our production of 2-Chloro-5-[[4,5-Dihydro-3-Methyl-5-Oxo-1-(4-Sulphophenyl)-1H-Pyrazol-4-Yl]Azo]Toluene-4-Sulphonic Acid, Barium Salt adheres to stringent quality protocols to ensure batch-to-batch consistency and purity for industrial applications. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing key parameters such as purity, heavy metal content, and specific identification tests.

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). This material is hygroscopic (moisture-sensitive) and light-sensitive (store away from light); therefore, containers must be kept tightly sealed to minimize exposure to atmospheric moisture and light to preserve product integrity.
