Industrial Applications of Xylenol orange tetrasodium salt
| Industry | Application | Process |
|---|---|---|
| Analytical Chemistry | Metal ion indicator | Used in complexometric titrations to detect metal ions (e.g., Zn²⁺, Bi³⁺, Pb²⁺), forming red complexes with target ions at pH 5–6; color changes to yellow at the endpoint |
| Environmental Monitoring | Water quality analysis | Employed as a chromogenic reagent for quantitative determination of trace metal contaminants in industrial wastewater via colorimetry or spectrophotometry |
| Pharmaceutical R&D | Biological metal ion detection | Applied in laboratory settings for chromogenic detection of calcium, zinc, and other metal ions in cells or biological samples to support studies on metal homeostasis mechanisms |
| Teaching Laboratories | Chemistry teaching reagent | Used in titration experiments within university or secondary school chemistry curricula to demonstrate complexation reactions and indicator color-change principles |
Manufacturing Quality Control of Xylenol orange tetrasodium salt
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantitative determination based on absorbance at characteristic wavelength (e.g., 570 nm) using molar absorptivity and Beer-Lambert law. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of trace metal impurities after acid digestion and matrix matching, using element-specific hollow cathode lamps. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential jump due to AgCl precipitation. |
| Sulfate Impurity | Gravimetric Analysis | Precipitation as BaSO4 under controlled pH and temperature, followed by filtration, drying, and weighing of the precipitate. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric titration based on stoichiometric reaction of iodine with water in pyridine/methanol medium. |
| pH of Aqueous Solution | pH Potentiometry | Measurement using calibrated glass electrode in a defined aqueous solution (e.g., 1% w/v) at 25 C. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue after high-temperature ashing (500-600 C) of sample in platinum crucible. |
| Iron Impurity | ICP-OES | Multi-element quantification after acid digestion, using plasma excitation and element-specific emission line intensities. |
| Loss on Drying | Thermogravimetry | Mass loss measured after drying at 105 C for 2 hours under controlled atmosphere, expressed as weight percent. |
| Organic Impurities | HPLC-UV | Separation on reversed-phase column with UV detection; purity assessed by peak area normalization against reference standard. |
| Appearance (Color and Clarity) | Visual Inspection | Comparison against standard color scale (e.g., APHA) and visual assessment of clarity in specified aqueous solution. |
| Solubility in Water | Qualitative Dissolution Test | Observation of complete dissolution in specified volume of water at 25 C within defined time, without residue or haze. |
