Industrial Applications of 3-(4-BROMO-PHENYL)-PROPIONIC ACID ETHYL ESTER
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Synthesis of anti-inflammatory drug intermediates | Used as an organic synthesis intermediate to prepare structural analogs of nonsteroidal anti-inflammatory drugs (NSAIDs) via coupling or substitution reactions to introduce aromatic bromo groups |
| Agrochemicals | Insecticide/fungicide intermediates | Applied in constructing brominated aromatic scaffolds for synthesizing biologically active agrochemicals |
| Organic Synthesis | Intermediates for liquid crystal materials or functional molecules | Employed in transition metal-catalyzed reactions such as Suzuki coupling to build functional organic molecules with complex aromatic systems |
Manufacturing Quality Control of 3-(4-BROMO-PHENYL)-PROPIONIC ACID ETHYL ESTER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by separation on capillary column and flame ionization detection relative to external standard. |
| Related Substances (Impurities) | Gas Chromatography (GC) with FID or Mass Spectrometry (GC-MS) | Separates and detects structurally related impurities (e.g., unreacted bromobenzene, phenylpropanoic acid, ethyl ester hydrolysis products) using retention time and/or mass spectral identification. |
| Residual Solvents (Ethanol, Toluene, etc.) | Headspace Gas Chromatography (HS-GC) | Quantifies volatile organic solvents by equilibrium partitioning into headspace followed by GC-FID analysis per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration based on iodine generation and stoichiometric reaction with water in anhydrous methanol-based solvent. |
| Acid Value | Acid-Base Titration (NaOH standard solution) | Measures free carboxylic acid content via neutralization with standardized sodium hydroxide solution using phenolphthalein or potentiometric endpoint detection. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma–Optical Emission Spectrometry (ICP-OES) | Simultaneous multi-element quantification after microwave-assisted acid digestion, based on element-specific atomic emission intensities. |
| Chloride Content | Ion Chromatography (IC) with Conductivity Detection | Separates and quantifies chloride ions after sample dissolution and dilution; detection relies on ionic conductivity of eluted anions. |
| Appearance & Color | Visual Inspection / Hazen (APHA) Color Scale | Assesses physical state (clear liquid), color intensity, and absence of particulates under controlled lighting against platinum-cobalt standards. |
| Refractive Index | Refractometry at 20 °C | Measures bending of light through the sample at specified temperature using a calibrated digital refractometer; correlates with purity and composition. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Determines mass per unit volume from resonant frequency shift of a vibrating U-shaped tube filled with sample at controlled temperature. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Measures non-volatile inorganic residue after controlled charring and sulfuric acid treatment followed by high-temperature incineration and weighing. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral molecules in solution; confirms enantiomeric purity if applicable (though compound is achiral, used for batch consistency verification). |
