Manufacturing Quality Control of 1-Chloro-2,4-dibromobenzene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies 1-chloro-2,4-dibromobenzene by retention time and peak area against a calibrated standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine-based reagent in anhydrous methanol. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by weighing residue after high-temperature ashing. |
| Chloride Impurities | Ion Chromatography (IC) | Separates and quantifies soluble chloride ions using conductivity detection after ion exchange. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures total heavy metal content by atomizing sample and detecting absorbance at characteristic wavelengths. |
| Acid-Value | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator. |
| Color | Visual Comparison or Hazen Color Scale | Evaluates color intensity by comparing sample appearance to platinum-cobalt standard solutions. |
| Density | Digital Density Meter | Determines mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light through liquid sample to infer purity and composition. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling contaminants by analyzing vapor phase above heated sample. |
| Residual Solvents | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies trace solvents based on retention time and mass spectral fragmentation. |
| Melting Point | Capillary Melting Point Apparatus | Determines solid-to-liquid transition temperature range as indicator of crystalline purity. |
