Industrial Applications of 3-Bromostyrene
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Used in the synthesis of drug molecules or active pharmaceutical ingredients | Employed as an aryl bromide in Suzuki, Heck, and other coupling reactions to construct complex molecular frameworks |
| Organic Synthesis | Served as a building block for synthesizing functional materials or fine chemicals | Incorporated into polymers via radical polymerization, coordination polymerization, or copolymerization to introduce styrenyl and bromo substituents |
| Materials Science | Used to prepare functional polymeric materials (e.g., flame retardant precursors, optoelectronic materials) | The bromine atom provides reactive sites for post-polymerization modification or crosslinking to enhance material performance |
| Agricultural Chemicals | Intermediate in the synthesis of pesticides or plant growth regulators | Utilized in nucleophilic substitution or transition metal-catalyzed coupling to install target structural motifs |
| Research Reagents | Standard substrate for developing new reactions or mechanistic studies | Evaluated for C–Br bond activation efficiency in palladium-, nickel-, and other transition metal-catalyzed systems |
Manufacturing Quality Control of 3-Bromostyrene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a calibrated column and carrier gas. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine is generated in situ to react stoichiometrically with water; endpoint detected amperometrically. |
| Residue on Ignition | Gravimetric Analysis | Sample is incinerated at 700-800 C, cooled in desiccator, and weighed to determine non-volatile inorganic residue. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities (e.g., brominated benzoic acids) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Comparison of sample color intensity against platinum-cobalt standard solutions using visual matching or absorbance at 430 nm. |
| Density at 20 C | Digital Density Meter | Measurement of mass per unit volume using oscillating U-tube principle with temperature-controlled sample cell. |
| Refractive Index at 20 C | Refractometry | Determination of light bending angle at air-sample interface using Abbe refractometer or digital equivalent calibrated with standard liquids. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element detection after acid digestion by measuring characteristic atomic emission wavelengths following plasma excitation. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions on an anion-exchange column with conductivity detection. |
| Aldehyde Impurity (e.g., benzaldehyde) | GC-MS | Separation by gas chromatography followed by mass spectrometric identification and quantification using selected ion monitoring. |
| Peroxide Value | Iodometric Titration | Oxidation of potassium iodide by peroxides to liberate iodine, titrated with standardized sodium thiosulfate solution. |
| Non-Volatile Residue | Evaporation and Gravimetry | Sample evaporated to dryness under controlled nitrogen flow at 105 C, cooled, and weighed to determine residual solids. |
