Semixylenol Orange CAS 19329670 High Purity China Suppliers and Factory
Semixylenol Orange is a premium, high-purity metallochromic indicator engineered for precision in complexometric titrations. Specifically designed for the detection of metal ions such as lead, zinc, and rare earth elements, it facilitates a sharp and distinct color transition from yellow in its free form to red when metal-bound. This high-contrast visual endpoint determination makes it an indispensable tool for EDTA titrations in rigorous analytical environments.
Beyond standard titrations, this versatile reagent is critical for trace metal analysis in environmental monitoring, metallurgical assessment, and biochemical research. With exceptional water solubility and stability across a diverse pH range, Semixylenol Orange ensures reproducible and accurate results, supporting both quantitative spectrophotometric measurements and qualitative laboratory testing in accordance with international regulatory standards.
