| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Used as a pharmaceutical intermediate in the synthesis of biologically active compounds (e.g., anti-inflammatory, antimicrobial, or anticancer candidates) | Integrated into target molecular structures via organic synthesis reactions such as amidation, esterification, or Suzuki coupling |
| Agrochemicals | Employed as an intermediate in the synthesis of novel herbicides or fungicides | Active molecular frameworks constructed via nucleophilic substitution or metal-catalyzed cross-coupling reactions |
| Materials Science | Serves as a precursor in the synthesis of liquid crystal materials or organic optoelectronic materials | Conjugated systems assembled through halogen-functional-group-involved coupling reactions (e.g., Heck, Sonogashira) |
| Organic Synthesis | General aryl bromide building block for constructing complex aromatic architectures | Bromine atom reactivity leveraged for metallation (e.g., lithiation, magnesiation) or palladium-catalyzed cross-coupling |
| 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 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., bromination by-products, oxidation products) relative to main peak using gradient HPLC-UV. |
| Residual Solvents | GC-FID | Detection and quantification of volatile organic solvents (e.g., toluene, methanol, ethyl acetate) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in a pyridine-methanol solvent system. |
| Heavy Metals | ICP-MS | Multi-element quantitative analysis of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity-based quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Determination of inorganic residue after controlled incineration at 700-800 C, followed by weighing of the residual ash. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing solid-to-liquid phase change in a capillary tube under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of visible particulates or discoloration against established reference standards. |
| Acid Value | Acid-Base Titration | Neutralization of carboxylic acid groups with standardized NaOH solution using phenolphthalein indicator or potentiometric endpoint detection. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to detect chiral impurities or enantiomeric excess (though compound is achiral, confirms absence of chiral contaminants). |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample to determine volume-based particle size distribution using Mie scattering theory. |
