Manufacturing Quality Control of alpha,alpha'-Dibromo-p-xylene
| 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 retention time and mass spectral fragmentation patterns. |
| Moisture Content | Karl Fischer Titration | Measures water content via stoichiometric reaction between water, iodine, and sulfur dioxide in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weighing of residual residue. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies metal impurities (e.g., Pb, Cd, Hg, As) by atomic emission intensity at characteristic wavelengths. |
| Acid Value | Acid-Base Titration with NaOH | Measures free acid content by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Bromine Content | Oxygen Flask Combustion followed by Potentiometric Titration | Converts organic bromine to bromide ion via combustion, then quantifies Br- by silver nitrate titration with potentiometric endpoint detection. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid using calibrated capillary apparatus per USP/EP guidelines. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against standard reference. |
| Solubility in Common Solvents | Qualitative Solubility Test | Evaluates dissolution behavior in specified solvents (e.g., chloroform, acetone) by visual observation after agitation and settling. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling residual solvents (e.g., methanol, dichloromethane) via equilibrium vapor phase analysis. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension using angular scattering pattern of laser beam. |
