Applications of 135-20-6
| Industry | Application | Process |
|---|---|---|
| Analytical Chemistry | Gravimetric determination of metal ions | Forms insoluble precipitates with metal ions such as copper, iron, and vanadium in acidic media; the precipitates are filtered, washed, dried or ignited, then weighed. |
| Analytical Chemistry | Extraction and separation of metal ions | Selectively separates metal ions such as Fe(III), Cu(II), and V(V) from solutions containing interfering ions (e.g., aluminum, chromium) via precipitation. |
| Analytical Chemistry | Masking agent in EDTA complexometric titration | Masks interfering ions such as Fe(III) and Cu(II) during the determination of aluminum, rare earth elements, etc., preventing indicator masking or precipitation interference. |
| Metallurgical Industry | Purification of metal salt solutions | Removes impurity metal ions—particularly iron and copper—via precipitation to enhance the purity of the primary metal product. |
| Pharmaceutical Industry | Detection and control of iron impurities in drug intermediates or active pharmaceutical ingredients (APIs) | Detects or removes trace iron impurities during API synthesis using cupferron, ensuring compliance with pharmaceutical quality standards. |
| Environmental Monitoring | Determination and removal of heavy metal ions in industrial wastewater | Enriches or quantifies trace heavy metals (e.g., copper, iron, vanadium) in wastewater via precipitation for water quality assessment or treatment. |
| Organic Synthesis | Metal scavenger in organic reactions | Precipitates residual metal catalysts or metal impurities following certain catalytic reactions. |
