Manufacturing Quality Control of 1-BROMO-2,5-DIFLUORO-4-METHYLBENZENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on mass spectral fragmentation patterns and retention behavior. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Measures volatile organic solvents by equilibrium partitioning into headspace gas followed by GC separation. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Determines water via electrochemical iodine generation and stoichiometric reaction with water in anhydrous medium. |
| Acidity (as HBr) | Acid-Base Titration with NaOH | Neutralizes acidic impurities (e.g., residual HBr) using standardized sodium hydroxide solution and potentiometric endpoint detection. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Detects trace metal contaminants by ionization in plasma and mass-to-charge ratio discrimination. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Measures residue after controlled evaporation of sample under specified temperature and vacuum conditions. |
| Chloride Content | Ion Chromatography (IC) with Conductivity Detection | Separates and quantifies chloride ions based on anion exchange retention and conductivity response. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Determines density from resonant frequency shift of a U-shaped glass tube filled with sample. |
| Refractive Index | Digital Refractometer | Measures refractive index by critical angle of total internal reflection at prism-sample interface. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Evaluates yellowness intensity by matching to APHA color standards or measuring absorbance at 430 nm. |
| Melting Point | Capillary Melting Point Apparatus | Determines phase transition temperature range by observing solid-to-liquid change under controlled heating rate. |
