Industrial Applications of 1,4-DIBROMO-2-BUTANOL
| Industry | Application | Process |
|---|---|---|
| Chemical Synthesis | Organic synthesis intermediate for pharmaceuticals, agrochemicals, and functional materials | Produced via reaction of 1,4-dibromobutane with ethylene oxide, followed by hydrolysis to yield 1,4-dibromo-2-butanol |
| Pharmaceutical Industry | Intermediate in the synthesis of antibiotics and antiviral agents | Functions as a bifunctional building block for bromine and hydroxyl group introduction in multistep syntheses |
| Agrochemical R&D | Precursor compound for insecticides and fungicides | Participates in condensation or substitution reactions as a halohydrin intermediate |
| Polymer Materials | Used in the synthesis of flame-retardant polymers or crosslinking agents | Leverages its difunctionality in polymerization to enhance flame retardancy |
| Fine Chemicals | Production of surfactants, lubricant additives, and other specialty chemicals | Undergoes esterification or etherification under controlled conditions to achieve functional modification |
Manufacturing Quality Control of 1,4-DIBROMO-2-BUTANOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 1,4-dibromo-2-butanol peak area relative to a calibrated standard curve. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine-sulfur dioxide reaction. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Separates and quantifies volatile organic impurities using headspace injection and FID detection. |
| Acidity (as HBr) | Acid-Base Titration with NaOH | Neutralizes acidic impurities (e.g., HBr) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Heavy Metals | ICP-OES | Detects trace metal contaminants (e.g., Pb, Fe, Cu) by measuring atomic emission intensities after acid digestion. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color to platinum-cobalt standards; measured as APHA units at 455 nm. |
| Specific Gravity | Digital Density Meter | Determines density ratio relative to water at 20/20 deg C using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light through liquid sample at 20 deg C to assess purity and concentration. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Determines residue mass after evaporation of a fixed sample volume under controlled conditions. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| Related Substances (Impurity Profile) | GC-MS | Identifies and quantifies structural analogs and degradation products via retention time and mass spectral matching. |
