Manufacturing Quality Control of ALPHA,ALPHA'-BIS(4-HYDROXYPHENYL)-1,4-DIISOPROPYLBENZENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase chromatography with UV detection at characteristic wavelength (e.g., 275 nm) and external standard calibration. |
| Related Substances (Impurities) | HPLC-UV or UPLC-MS | Separates and detects structurally related impurities (e.g., mono-hydroxy analogs, isomers, dealkylated products) via chromatographic resolution and UV/MS identification. |
| Moisture Content | Karl Fischer Titration (Coulometric) | Electrochemical titration quantifying water based on iodine generation and stoichiometric reaction with water in anhydrous methanol/pyridine medium. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures non-volatile inorganic residue after controlled high-temperature ashing (700–800 °C) and subsequent gravimetric determination. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS or ICP-OES | Quantifies trace metal contaminants by plasma ionization followed by mass spectrometric or optical emission detection with multi-element capability. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration | Separates and quantifies chloride ions using anion-exchange column with conductivity detection, or via silver nitrate titration with endpoint detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid phase transition using calibrated capillary tube method per USP <741>. |
| Appearance (Color & Clarity) | Visual Inspection against Standard Solutions | Assesses physical state, color (e.g., APHA/Pt-Co scale), and clarity in solution (e.g., 1% w/v in ethanol) under controlled lighting conditions. |
| Organic Volatile Impurities (e.g., residual solvents) | GC-FID or GC-MS | Detects and quantifies volatile organic residues (e.g., toluene, isopropanol) using gas chromatography with flame ionization or mass spectrometric detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic sulfate residue after sulfuric acid treatment and high-temperature incineration, indicating inorganic salt content. |
| pH of Aqueous Suspension | pH Meter Measurement | Determines acidity/basicity of a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode, reflecting acidic/basic impurity profile. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension using Mie scattering theory and angular intensity analysis of laser light. |
| Specific Optical Rotation | Polarimetry | Quantifies chiral purity (if applicable) or detects optically active impurities by measuring rotation angle of plane-polarized light through a standardized solution. |
| Loss on Drying (LOD) | Thermogravimetric Analysis (TGA) or Oven Drying | Determines volatile content (water + solvents) by weight loss upon heating under controlled temperature and atmosphere (e.g., 105 °C, 2 h). |
