Manufacturing Quality Control of 4-(TERT-BUTYL)PHENYLACETYLENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile organic impurities are vaporized in sealed vials and quantified by GC-FID or GC-MS against calibrated standards. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Sample digested in acid matrix; elemental emission intensities measured at characteristic wavelengths and compared to calibration curve. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Anionic impurities separated on an ion-exchange column and quantified via suppressed conductivity detection relative to chloride standard. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample ignited at 700-800 C; residue weight measured after cooling in desiccator and expressed as percentage of original sample. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range over which solid transforms to liquid under controlled heating rate. |
| Appearance (Color and Clarity) | Visual Inspection against Standard Solutions | Sample dissolved in specified solvent and assessed for color (Hazen/APHA units) and presence of particulates or haze under controlled lighting. |
| Acid Value | Acid-Base Titration with NaOH (Ethanol solvent) | Free acidic impurities neutralized with standardized sodium hydroxide solution; endpoint detected potentiometrically or with phenolphthalein. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Impurity profiling using reversed-phase C18 column and gradient elution; detection at 254 nm with peak identification/quantification vs reference standards. |
| Bulk Density | ASTM D1895 Method A (Tapped Density) | Mass per unit volume measured after mechanically tapping a graduated cylinder containing the powder until volume stabilizes. |
| Particle Size Distribution | Laser Diffraction (Dry Dispersion) | Particles dispersed by air jet and size distribution calculated from angular scattering pattern of laser beam using Mie theory. |
