| Industry | Application | Process |
|---|---|---|
| Chemical | As an organic synthesis intermediate | Participates in esterification, amidation, and other reactions to produce phthalate derivatives |
| Analytical Chemistry | Used as a reference standard or buffer component | Formulated into pH buffer solutions for titration or chromatographic analysis |
| Pharmaceuticals | As a drug synthesis precursor or excipient | Applied in synthesizing active pharmaceutical ingredients containing phthalate structures or enteric coating materials |
| Materials Science | For preparing polymer additives | Serves as a precursor for plasticizers or stabilizers in polymer modification processes |
| Environmental Engineering | As a water quality reference standard or degradation study compound | Used in simulated wastewater treatment experiments to evaluate biological or chemical degradation efficiency |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Na salt content) | Acid-base titration | Neutralization of phthalate anion with standardized HCl after acidification; endpoint detected potentiometrically or with indicator. |
| Moisture content | Karl Fischer titration | Quantitative reaction of water with iodine and sulfur dioxide in pyridine/methanol medium; coulometric or volumetric detection. |
| pH of aqueous solution | pH meter measurement | Electrochemical measurement of hydrogen ion activity in a 1% w/v aqueous solution at 25 C. |
| Heavy metals (as Pb) | Atomic absorption spectroscopy (AAS) | Quantification of total heavy metals via flame or graphite furnace AAS after acid digestion and matrix matching. |
| Sulfate (SO4) impurity | Gravimetric analysis | Precipitation of sulfate as BaSO4 under controlled conditions, followed by drying and weighing. |
| Chloride (Cl) impurity | Potentiometric titration with AgNO3 | Titration with silver nitrate using silver electrode; chloride forms insoluble AgCl, causing potential inflection. |
| Iron (Fe) content | ICP-OES | Multi-element quantification after sample digestion; Fe emission intensity measured at characteristic wavelength (e.g., 259.94 nm). |
| Loss on drying (LOD) | Thermogravimetric analysis (TGA) | Mass loss measured upon heating to 105 C for 2 h under controlled atmosphere; reflects volatile and hygroscopic components. |
| Residue on ignition | Ignition and gravimetry | Sample ignited at 600-700 C to oxidize organics; inorganic residue weighed after cooling in desiccator. |
| Organic impurities (related substances) | HPLC-UV | Separation on reversed-phase column with UV detection at 220-254 nm; comparison to reference standards and retention time matching. |
| Particle size distribution | Laser diffraction | Analysis of light scattering pattern from dispersed particles in liquid medium to determine volume-based size distribution. |
| Bulk density | Tap density measurement | Mass of sample divided by its volume after standardized tapping (ASTM D1895); measures flowability and packing behavior. |
