Industrial Applications of 3-BROMO-5-METHYLBENZONITRILE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key intermediate in the synthesis of anticancer agents (e.g., analogues of BTK inhibitors) | Brominated aryl nitriles participate in Suzuki coupling, cyanide hydrolysis, or reduction to construct targeted molecular scaffolds |
| Agrochemical Intermediates | Aromatic heterocyclic precursor for synthesizing novel insecticides and fungicides | Cyano group conversion introduces pharmacophores such as amides and tetrazoles; bromine atom provides a site for further functionalization |
| Organic Synthesis | Multifunctional building block for preparing poly-substituted arenes containing bromo, cyano, and methyl groups | Typical processes include Pd-catalyzed cross-coupling (e.g., Heck, Stille), nucleophilic substitution, and cyano derivatization (e.g., reaction with sodium azide to form tetrazoles) |
Manufacturing Quality Control of 3-BROMO-5-METHYLBENZONITRILE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of impurities using reversed-phase C18 column and gradient elution; detection at 220 nm. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling and FID | Headspace equilibration followed by GC separation to quantify volatile organic solvents (e.g., methanol, acetone, toluene). |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomization and excitation of metals in argon plasma; quantification via element-specific emission wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anions on an ion-exchange column and detection via suppressed conductivity. |
| Residue on Ignition | Gravimetric analysis after high-temperature ashing | Sample ignited at 700-800 C to remove organic matter; residual inorganic ash weighed as sulfate-free residue. |
| Melting Point | Capillary melting point apparatus | Thermal transition observed visually or automatically as the temperature range over which solid transforms to liquid. |
| Appearance | Visual inspection against standard white background | Assessment of physical state, color, and presence of visible particulates or discoloration under controlled lighting. |
| Bulk Density | Tap density measurement (ASTM D1895) | Mass per unit volume of powder after standardized tapping; measured using calibrated graduated cylinder and mechanical tap device. |
| Particle Size Distribution | Laser Diffraction (Dry Dispersion) | Analysis of scattered laser light intensity patterns to calculate particle size distribution based on Mie theory. |
| pH of Aqueous Suspension | pH meter measurement | Electrochemical measurement of hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) at 25 C. |
