Manufacturing Quality Control of 1,3,5-TRIETHYNYLBENZENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID or MS detection | Quantifies 1,3,5-triethynylbenzene peak area relative to a calibrated standard using retention time and response factor. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatilizes and separates residual solvents (e.g., THF, acetone) from the solid sample; quantified via external/internal calibration. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; measures trace moisture content. |
| Heavy Metals (Pb, Cd, Hg, Cr, As) | Inductively Coupled Plasma–Mass Spectrometry (ICP-MS) | Sample digested in acid matrix; elements ionized in plasma and detected by mass-to-charge ratio with ultratrace sensitivity. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separates chloride anions from other ionic impurities in solution; quantified via calibrated conductivity response. |
| Acid Value | Potentiometric Titration with KOH in isopropanol/toluene | Measures acidic impurities (e.g., carboxylic acids) by titration with standardized alcoholic KOH; endpoint determined by pH inflection. |
| Melting Point | Differential Scanning Calorimetry (DSC) | Detects thermal transition of crystalline phase; melting onset and range indicate purity and polymorphic consistency. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash Method) | Measures non-volatile inorganic residue after high-temperature combustion in presence of sulfuric acid; reflects inorganic ash content. |
| Particle Size Distribution | Laser Diffraction (Dry Dispersion) | Analyzes scattered laser light intensity vs. angle to determine volume-based particle size distribution of powdered material. |
| Organic Volatile Impurities (e.g., benzene, acetylene derivatives) | GC–MS with Cold Trap Preconcentration | Traps and thermally desorbs low-boiling organics; identification and quantification via spectral library matching and calibration curves. |
