Manufacturing Quality Control of BIS(4-NITROPHENYL) SULFIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Identifies and quantifies impurities (e.g., nitrobenzene, thiophenol, disulfides) via gradient HPLC-UV with relative retention time and response factor correction. |
| Moisture Content | Karl Fischer Titration | Measures water content by electrochemical titration with iodine, where water reacts stoichiometrically with iodine and sulfur dioxide in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after controlled ashing at 700-800 C, expressed as mass percent of original sample. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies total heavy metals (Pb, Cd, Hg, As, Cr) by plasma emission spectroscopy following acid digestion and matrix-matched calibration. |
| Chloride Impurity | Potentiometric Titration | Measures chloride ions using silver nitrate titrant with silver-silver chloride electrode; endpoint detected by potential inflection. |
| Sulfate Impurity | Turbidimetric Analysis | Quantifies sulfate as barium sulfate precipitate; absorbance measured at 420 nm and compared to sulfate standard curve. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, based on light transmission through capillary tube under controlled heating. |
| Organic Volatile Impurities | GC-FID | Detects residual solvents (e.g., toluene, DMF, methanol) using gas chromatography with flame ionization detection and internal standard calibration. |
| Bulk Density | USP <616> Method I | Measures mass per unit volume of freely settled powder in standardized cylinder; calculated from tared weight and calibrated volume. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution by measuring angular variation in intensity of laser light scattered by dispersed particles in air or liquid medium. |
| pH of Aqueous Suspension | pH Meter | Determines acidity/basicity of saturated aqueous suspension using calibrated glass electrode pH meter at 25 C. |
