| Organic Synthesis | Grignard Reagent Preparation | Reacted with magnesium metal to prepare 4-methoxybutylmagnesium bromide, employed for introducing the 4-methoxybutyl group into organic molecules |
| Agrochemicals | Agrochemical Intermediates | Applied in synthesizing ether-containing agrochemical active ingredients, serving as a modifying group to enhance lipophilicity and metabolic stability |
Manufacturing Quality Control of 1-Bromo-4-methoxybutane
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water in the sample. |
| Acidity (as HBr) | Acid-Base Titration with NaOH | Neutralization of acidic impurities (e.g., residual HBr) using standardized sodium hydroxide solution and potentiometric endpoint detection. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a known sample mass under controlled temperature and pressure, followed by weighing of non-volatile residue. |
| Color | Visual Comparison or Spectrophotometry (APHA Scale) | Comparison of sample color against platinum-cobalt standard solutions or measurement of absorbance at 455 nm. |
| Density | Oscillating U-tube Densitometry | Measurement of sample density via resonant frequency shift of a vibrating U-shaped tube filled with the liquid. |
| Refractive Index | Refractometry (Abbe Refractometer) | Determination of refractive index by measuring the critical angle of total internal reflection at the prism-sample interface. |
| Boiling Range | Distillation (Micro or Semi-micro ASTM D1078) | Fractional distillation under reduced pressure to determine initial and final boiling points corresponding to 5% and 95% recovery. |
| Heavy Metals (as Pb) | ICP-OES after Acid Digestion | Quantification of trace metals following microwave-assisted nitric acid digestion and multi-element plasma emission spectroscopy. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation of anions on an ion-exchange column and quantification via conductivity response relative to chloride standards. |
| Residual Solvents (e.g., MeOH, THF) | Headspace Gas Chromatography (HS-GC) | Thermal equilibration of sample in sealed vial, followed by GC analysis of volatile organic impurities in the headspace vapor. |
| Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution of the compound in a defined cell path length and concentration. |
