Manufacturing Quality Control of 3-METHYL-3-TRIMETHYLSILYLOXY-1-BUTYNE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area relative to calibration standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Residue on Evaporation | Gravimetric Analysis | Determines non-volatile impurities by evaporating sample under controlled conditions and weighing residue. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange and conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Atomizes and excites sample in plasma; measures element-specific emission intensities for multi-element quantification. |
| Refractive Index | Refractometry | Measures bending of light through liquid sample at specified temperature to assess purity and consistency. |
| Density | Oscillating U-tube Densitometry | Determines mass per unit volume from resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Compares sample color to platinum-cobalt standard scale using visual assessment or absorbance at 455 nm. |
| Distillation Range | Vacuum Distillation | Determines boiling point interval under reduced pressure to verify volatility profile and detect low/high boilers. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Extracts and quantifies volatile organic solvents via equilibrium partitioning into headspace before GC analysis. |
| Organosilicon Impurities (e.g., HMDS, TMCS) | Gas Chromatography-Mass Spectrometry (GC-MS) | Separates volatile impurities by GC and identifies/quantifies them using mass spectral fragmentation patterns. |
