Manufacturing Quality Control of (2-BROMOPHENYLETHYNYL)TRIMETHYLSILANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area against calibrated standard. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatiles are partitioned into headspace and separated/quantified by GC. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Elements are atomized and ionized in plasma; isotopic masses are detected quantitatively. |
| Chloride Impurity | Ion Chromatography (IC) | Anions are separated on ion-exchange column and detected by conductivity. |
| Residual Catalyst (Pd) | ICP-OES | Sample digested and atomized; element-specific emission intensities measured. |
| Acidity (as HBr) | Acid-Base Titration with NaOH | Free acid content determined by neutralization with standardized sodium hydroxide. |
| Color | Visual Comparison or Spectrophotometry (APHA scale) | Compares sample color to platinum-cobalt standards or measures absorbance at 455 nm. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change under controlled heating. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral impurities or enantiomeric excess. |
| Volatile Impurities (non-solvent) | GC-MS | Separation followed by mass spectral identification and semi-quantification of unknown volatiles. |
| Residue on Ignition | Gravimetric Analysis | Non-volatile inorganic residue measured after high-temperature ashing and weighing. |
