Manufacturing Quality Control of 1,1-DIPHENYLETHANOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 1,1-diphenylethanol by separation and flame ionization detection relative to a certified reference standard. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities (e.g., benzophenone, diphenylmethane) based on retention time and mass spectral matching. |
| Water Content | Karl Fischer Titration (Coulometric) | Determines trace water via electrochemical titration using iodine generated in situ proportional to water content. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures non-volatile inorganic residue after high-temperature ashing at 700-800 C. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies elemental impurities (e.g., Pb, Cd, Hg, As) by atomic emission intensity following acid digestion. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Evaluates yellowness by comparing sample absorbance at 430 nm to APHA platinum-cobalt standard solutions. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Specific Optical Rotation | Polarimetry | Determines chiral purity by measuring rotation of plane-polarized light at 20 C using sodium D-line (589 nm). |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Quantifies volatile organic solvents (e.g., toluene, ethanol) by equilibrium vapor-phase analysis. |
| Chloride Content | Ion Chromatography (IC) with Conductivity Detection | Separates and quantifies chloride ions after sample dissolution and filtration using anion-exchange column. |
| Bulk Density | Volumetric Method (ASTM D1895) | Measures mass per unit volume of freely settled powder using a calibrated cylinder and balance. |
