| Materials Science | Synthesis of organic semiconductor materials | Palladium-catalyzed coupling reactions link 4-bromoterphenyl to other conjugated units to build hole-transport or emissive materials |
| Medicinal Chemistry | Synthesis of drug candidate molecules containing the terphenyl motif | Serves as a key intermediate in drug molecule scaffold construction, enabling target compound synthesis via multistep routes |
| Nanotechnology | Surface functionalization of carbon nanotubes or graphene | Halogen–metal coupling reactions graft 4-bromoterphenyl onto nanomaterial surfaces to enhance dispersion and electronic properties |
Manufacturing Quality Control of 4-BROMO-P-TERPHENYL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison with a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., brominated isomers, residual biphenyls) relative to main peak using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., toluene, THF, methanol) by gas chromatography with flame ionization detection. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration measuring water content via stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (Pb, Cd, Hg, As, Cr) after acid digestion, based on atomic emission intensity at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity-based detection of chloride ions using anion-exchange column and suppressed conductivity detector. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing solid-to-liquid phase change under controlled heating rate per USP <741>. |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic ash content by high-temperature incineration followed by precise weighing of residual residue. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles against defined standards under controlled lighting conditions. |
| Bulk Density | Tap Density Measurement | Determination of mass per unit volume after standardized tapping of a known powder mass in a calibrated cylinder. |
| Particle Size Distribution | Laser Diffraction | Analysis of size distribution based on angular dependence of scattered laser light from dispersed particles in air or liquid medium. |
| Sulfated Ash | Gravimetric Analysis | Quantification of inorganic residue after ignition with sulfuric acid pretreatment, per USP <281>. |
