Manufacturing Quality Control of 4-Bromo-1-butene
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, transparency, and presence of suspended particles or precipitates under natural light or standard light source. Typically a colorless to pale yellow liquid. |
| Content/Purity | Gas Chromatography (GC) | Using capillary columns (e.g., HP-5, DB-624), with FID detector, qualitative analysis by retention time and quantitative analysis by peak area normalization or external standard method for main component content. |
| Solvent Residue | Gas Chromatography (GC) | Using headspace sampling or solution sampling to detect possible residual organic solvents (e.g., methanol, ethanol, acetone), and determine compliance with requirements based on pharmacopoeia or enterprise standards. |
| Moisture | Karl Fischer Titration | Determine moisture content precisely by measuring the reaction between iodine and sulfur dioxide in the presence of pyridine and methanol through coulometric titration. |
| Acid Value/Acidity | Acid-Base Titration | Determine free acid in the sample using standard sodium hydroxide ethanol solution, with phenolphthalein as indicator or endpoint determination by potentiometry, calculating the acid value based on HBr or other acids. |
| Density | Pycnometer Method or Hydrometer Method | Determine the mass per unit volume at a specified temperature (e.g., 20°C) to assist in judging purity and consistency of the substance. |
| Refractive Index | Refractometer Method | Measure refractive index using an Abbe refractometer at standard temperature, used as a physical constant for identification and preliminary assessment of purity. |
| UV Absorption | UV-Visible Spectrophotometry (UV-Vis) | Determine absorbance at specific wavelengths (e.g., 200–300 nm) to evaluate conjugated structures or impurity absorption, controlling related substances. |
| Related Substances/Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Combine GC separation capability with MS qualitative ability to identify and semi-quantitatively detect possible isomers, degradation products, or by-products from synthesis. |
| Boiling Point/Range | Distillation Method | Determine initial boiling point and dry point using a standard distillation apparatus to assess volatility and component distribution, reflecting purity and consistency of the product. |
