Industrial Applications of 3,5-Dibromophenol
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Intermediate for synthesizing antibacterial and antifungal agents | Used as an aromatic ring bromination intermediate in nucleophilic substitution or coupling reactions (e.g., Suzuki coupling) to prepare active pharmaceutical ingredients |
| Agrochemicals | Intermediate for synthesizing fungicides and insecticides | Applied to construct brominated aromatic frameworks, enabling further functional group transformations to introduce heterocycles or alkyl side chains |
| Materials Science | Raw material for flame retardant synthesis | Reacted with epoxy resins or polycarbonate precursors to incorporate bromine atoms and enhance flame retardancy |
| Organic Synthesis | Multifunctional synthon | Used to prepare derivatives such as 3,5-dibromophenyl ether and 3,5-dibromoaniline, serving as substrates in cross-coupling reactions |
| Analytical Chemistry | Reference standard or derivatization reagent | Employed as a chromatographic reference standard or for bromination derivatization of phenolic compounds to improve detection sensitivity |
Manufacturing Quality Control of 3,5-Dibromophenol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 275 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., mono-bromo isomers, dibromo isomers, phenol) relative to the main peak using gradient elution. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., methanol, acetone, toluene) by gas chromatography with flame ionization detection. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of water with iodine and sulfur dioxide in pyridine/methanol medium. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Cr after acid digestion, using plasma excitation and atomic emission detection. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity-based detection of chloride ions after sample dissolution and filtration. |
| Sulfated Ash | Gravimetric Analysis | Residue mass measurement after high-temperature incineration (500-600 C) of the sample in a platinum crucible. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light against standard references. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a 1% w/v suspension in distilled water using a calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of size distribution in dispersed powder sample via angular scattering pattern of laser beam. |
| Organic Volatile Impurities (Total) | GC-FID | Sum of quantified residual solvents using a single calibration standard and defined method parameters per ICH Q3C. |
