General description
Application
- Spectrophotometric Analysis: Chromotropic acid disodium salt dihydrate is used in spectrophotometric methods for detecting and quantifying metal ions. Studies have shown its effectiveness in forming stable complexes with metal ions such as thorium, which can then be analyzed spectrophotometrically. This application is essential for environmental and industrial monitoring of metal contaminants (Issa et al., International Journal of Pharmaceutical Sciences Review and Research, 2022).
Features and Benefits
- Increased efficiency – Eliminates time and effort of loosening hardened powders
- Safety – Eliminates tools of force used to break up clumps
- Ecology – Reduces waste as it does not stick to the packaging
- Economy – Faster preparation and solvation increase productivity and reduce costs
- Assured Quality – Excellent, expert-tested quality with no anti-caking agents
- Flexible volumes – Available from research amounts to scale-up quantities
