Industrial Applications of 4-broMo-3,5-difluorobenzonitrile
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Chemicals | Pharmaceutical Intermediates | Serves as a building block for synthesizing fluorinated drug molecules; complex drug structures are constructed via coupling reactions (e.g., Suzuki coupling) at the bromine site. |
| Agrochemicals | Agrochemical Intermediates | Used in synthesizing fluorinated benzoylurea- or benzamide-based insecticides and herbicides; fluorine and cyano groups are incorporated to optimize biological activity. |
| Organic Synthesis | Organic Synthesis Building Block | Enables nucleophilic substitution or metal-catalyzed cross-coupling reactions at the aromatic bromine site to introduce additional functional groups for target molecule construction. |
| Materials Science | Monomer for Functional Materials | Applied in synthesizing novel organic optoelectronic or liquid crystalline materials; fluorine atoms modulate material energy levels via their electron-withdrawing effect. |
Manufacturing Quality Control of 4-broMo-3,5-difluorobenzonitrile
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 220-254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., acetone, methanol, toluene) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and others after acid digestion, using plasma optical emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Ignition at 700-800 C followed by weighing of non-volatile inorganic residue after sulfuric acid treatment. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of sample against specified criteria (e.g., white to off-white crystalline powder). |
| Particle Size Distribution | Laser Diffraction | Measurement of size distribution in dry or wet dispersion mode using Mie scattering theory. |
| Bulk Density | Tap Density Tester | Determination of mass per unit volume after controlled tapping per USP <616>. |
| Organic Volatile Impurities (OVI) | GC-MS | Screening and semi-quantitative identification of unknown volatile impurities using mass spectral library matching. |
