Manufacturing Quality Control of 4,4'-Bis(hydroxymethyl)biphenyl
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., mono-hydroxymethyl, tri-hydroxymethyl, and des-methyl analogs) using gradient HPLC-UV. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration based on iodine consumption in a pyridine/methanol solvent system to determine water content. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 700-800 C to constant weight and measuring non-volatile inorganic residue as percentage of original mass. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy after acid digestion; measures absorbance of ground-state atoms at characteristic wavelength. |
| Chloride Content | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Sample charred, treated with sulfuric acid, ignited at 600-700 C, and residue weighed as sulfate ash. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as temperature at which solid phase fully converts to liquid. |
| Appearance | Visual Inspection | Assessment under controlled white light against standard color/opacity references for clarity, color, and presence of particulates. |
| Organic Volatile Impurities | GC-FID | Headspace or direct injection GC with flame ionization detection to identify and quantify residual solvents (e.g., methanol, toluene). |
| Acid Value | Acid-Base Titration | Titration with standardized KOH solution in ethanol/isopropanol using phenolphthalein indicator to determine free carboxylic acid equivalents. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity vs. angle to calculate volume-based particle size distribution in dry or wet dispersion mode. |
