Industrial Applications of 3,5-DibroMo-biphenyl
| Industry | Application | Process |
|---|---|---|
| Organic Synthesis | Intermediate for the production of liquid crystal materials, OLED materials, and pharmaceutical compounds | Used in aryl bromide coupling reactions (e.g., Suzuki, Ullmann coupling) or as a bromine source in substitution/addition reactions |
| Liquid Crystal Materials | Rigid biphenyl core structural unit in liquid crystal monomer synthesis | Applied in metal-catalyzed coupling with functionalized aromatic rings (e.g., bearing cyano or alkoxy groups) to construct liquid crystal molecular frameworks |
| Pharmaceutical R&D | Structural modification intermediate for potential antibacterial and antitumor active compounds | Employed as an aryl bromination site in palladium-catalyzed cross-coupling to introduce heterocycles or functional groups for pharmacological optimization |
| Pesticide Development | Structural building block in the design of novel insecticides and fungicides | Applied in nucleophilic substitution or transition-metal-catalyzed reactions to attach active moieties (e.g., triazole, pyrimidine) |
| Polymer Materials | Copolymerizable monomer for specialty engineering plastics and flame-retardant polymers | Used in condensation polymerization with bisphenols or diamines to incorporate bromine atoms and enhance flame retardancy |
Manufacturing Quality Control of 3,5-DibroMo-biphenyl
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies 3,5-dibromobiphenyl peak area relative to calibration standards using retention time and response factor. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on mass spectral fragmentation patterns and retention times. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Measures volatile organic solvents (e.g., toluene, methanol) by equilibrium vapor phase analysis. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration with iodine-based reagent stoichiometry. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies metal impurities (e.g., Pb, Cd, Hg, As) by atomic emission intensity at characteristic wavelengths. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using controlled heating and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under standardized lighting and viewing conditions. |
| Ash Content | Gravimetric Analysis (Ignition at 550 C) | Measures inorganic residue after high-temperature combustion and subsequent weighing. |
| Acid Value | Potentiometric Titration with KOH in ethanol | Quantifies acidic impurities by titration with standardized potassium hydroxide solution using pH endpoint detection. |
| Bromine Content | Oxygen Flask Combustion followed by Potentiometric Titration | Determines total bromine via combustion, absorption in alkali, and titration of bromide with silver nitrate. |
| Particle Size Distribution | Laser Diffraction Particle Size Analyzer | Measures size distribution based on angular variation of laser light scattering from dispersed particles. |
