Manufacturing Quality Control of 4-Mercaptophenol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies 4-hydroxybenzenethiol by reversed-phase HPLC with UV detection at ~280 nm, using external standard calibration. |
| Appearance | Visual Inspection | Assesses physical state and color against a white background under controlled lighting; acceptable as off-white to light yellow crystalline solid. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity via comparison to reference value (63-67 C). |
| Water Content | Karl Fischer Titration | Measures trace water by coulometric or volumetric titration with iodine-based reagent, based on stoichiometric reaction with water. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weighing of residual non-volatile matter. |
| Heavy Metals | ICP-OES | Quantifies Pb, Cd, Hg, As, and other regulated metals after acid digestion, using plasma excitation and elemental emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection after sample dissolution and filtration. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 in acidic medium, followed by filtration, drying, and gravimetric determination. |
| Related Substances | HPLC-DAD | Detects and quantifies structurally related impurities (e.g., quinones, disulfides, oxidation products) using HPLC with diode-array detection. |
| Odor | Organoleptic Assessment | Evaluates characteristic thiol odor intensity and character by trained personnel under standardized conditions; deviation indicates degradation. |
| pH of Aqueous Suspension | pH Meter | Measures pH of a defined suspension (e.g., 1% w/v in water) to assess acidity/basicity arising from impurities or decomposition products. |
| Loss on Drying | Thermogravimetric Analysis | Determines volatile content (e.g., solvent residues, moisture) by measuring mass loss upon heating at 105 C under controlled atmosphere. |
