Industrial Applications of 2-BroMo-1,3-diMethyl-4-nitrobenzene
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Structural building block for synthesizing active pharmaceutical ingredients (APIs), including anti-inflammatory and antineoplastic agents | Introduced into the target molecular scaffold via nucleophilic substitution or transition-metal-catalyzed cross-coupling reactions (e.g., Suzuki, Heck) |
| Agrochemical Intermediates | Building block for brominated nitroaromatic moieties in insecticides and fungicides | Prepared through multistep aromatic electrophilic substitutions, including nitration, bromination, and methylation, to yield specific agrochemical compounds |
| Organic Synthesis | Multifunctional aromatic building block for C–C, C–N, and C–O bond formation | Subjected to palladium-catalyzed cross-coupling; or functionalized via reduction/substitution of nitro and bromo groups to expand derivative libraries |
Manufacturing Quality Control of 2-BroMo-1,3-diMethyl-4-nitrobenzene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Related Substances (Impurities) | HPLC-UV or GC-FID | Separation and quantification of structurally related impurities (e.g., isomers, residual precursors, dehalogenated by-products) using retention time matching and relative response factors. |
| Residual Solvents | GC-FID or GC-MS | Headspace GC analysis with flame ionization detection (or mass spectrometry) to quantify volatile organic solvents (e.g., dichloromethane, toluene, methanol) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with water in anhydrous methanol-based medium. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification after acid digestion and dilution, leveraging high sensitivity and isotopic resolution for trace metal contaminants per ICH Q3D. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Analysis | Incineration at 700–800 °C followed by sulfuric acid treatment and weighing of inorganic residue to assess inorganic impurities. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement using controlled heating rate; deviation from literature value (104–106 °C) indicates purity or polymorphic issues. |
| Chloride Impurity (as Cl⁻) | Ion Chromatography (IC) or Potentiometric Titration | Anion separation and quantification via conductivity detection (IC), or argentometric titration with silver nitrate endpoint detection. |
| Acid Value (Free Acid) | Acid-Base Titration (NaOH, phenolphthalein) | Neutralization of acidic impurities (e.g., residual HBr, nitric acid) with standardized sodium hydroxide solution. |
| Appearance & Color | Visual Inspection / Hazen (APHA) Color Scale | Subjective assessment against water standard (appearance) and spectrophotometric comparison to platinum-cobalt standards for yellowness index. |
| Bulk Density & Tap Density | ASTM D1895 | Gravimetric measurement of mass per unit volume before and after standardized mechanical tapping to assess powder flow and handling properties. |
| Particle Size Distribution | Laser Diffraction (Malvern Mastersizer) | Analysis of scattered light intensity patterns to determine volumetric particle size distribution in dispersed solid samples. |
| Optical Rotation (if chiral impurity suspected) | Polarimetry | Measurement of rotation of plane-polarized light to detect chiral contaminants; compound is achiral but method verifies absence of optically active impurities. |
| Elemental Analysis (C, H, N, Br) | Combustion Analysis (CHNBr Analyzer) | High-temperature combustion followed by gas chromatographic or thermal conductivity detection of CO₂, H₂O, N₂, and halogen-specific detection (e.g., microcoulometric). |
