Manufacturing Quality Control of 4-ETHYNYL-1,1'-BIPHENYL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative separation and detection based on volatility and retention time relative to certified reference standard. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Volatile impurities partitioned into headspace gas and quantified by calibrated GC-FID or GC-MS. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomization and excitation of metals in plasma; quantification via element-specific emission intensities. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Anion separation on ion-exchange column followed by quantitative conductivity measurement. |
| Acid-Base Impurities | Acid-Base Potentiometric Titration | Titration with standardized NaOH or HCl while monitoring pH change to determine neutralizable acidic or basic species. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Sample ignited at 700-800 C after sulfuric acid treatment; residual inorganic mass measured by weight difference. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually as solid-to-liquid phase change under controlled heating rate. |
| Appearance | Visual Inspection (against white/black background) | Assessment of physical state, color, and presence of particulates or discoloration under standardized lighting. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution. |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Analysis of angular scattering pattern of laser beam passed through dispersed sample to calculate size distribution. |
| Organic Volatile Impurities (Total) | Gas Chromatography (GC) with Thermal Desorption | Thermal desorption of volatiles from solid sample followed by GC-FID quantification against calibration standards. |
