Industrial Applications of 2,5-DIBROMO-1,3-DIFLUOROBENZENE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Used in the synthesis of active pharmaceutical ingredients (APIs), including antitumor agents and kinase inhibitors | Serves as an aromatic brominated/fluorinated building block in cross-coupling reactions such as Suzuki and Heck couplings |
| Agrochemical Intermediates | Used to prepare novel fluorinated and brominated heterocyclic insecticides and fungicides | Introduced into the agrochemical molecular scaffold via nucleophilic substitution or metal-catalyzed coupling to enhance lipophilicity and biological activity |
| Organic Luminescent Materials | Functions as a conjugated small-molecule building block in electron-transport or emissive layers of OLED devices | Undergoes bromine-directed cyclization or polymerization to form thermally stable, high-mobility fluorinated and brominated aromatic derivatives |
Manufacturing Quality Control of 2,5-DIBROMO-1,3-DIFLUOROBENZENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against certified reference standard under optimized chromatographic conditions. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of structurally related impurities using reverse-phase column and UV absorbance at 254 nm. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) with FID | Volatile organic solvents are extracted into headspace and quantified by GC-FID using calibrated standards. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water in the sample. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element detection based on characteristic atomic emission lines after acid digestion and plasma atomization. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anions on ion-exchange column followed by quantitative detection via electrical conductivity. |
| Acid-Base Impurities | Acid-Base Potentiometric Titration | Titration with standardized NaOH or HCl to determine total acidic or basic functional group content. |
| Melting Point | Capillary Melting Point Determination | Thermal transition observed visually or automatically as solid-to-liquid phase change under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against specified criteria under standardized lighting conditions. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Mass difference measured before and after high-temperature ashing to determine inorganic residue content. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light caused by chiral molecules in solution. |
| Bulk Density | USP <616> Bulk and Tapped Density | Determination of mass per unit volume for powder form using standardized tapping and volumetric methods. |
