Manufacturing Quality Control of 3,5-Bis(bromomethyl)toluene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identification and semi-quantitation of impurities by retention time and mass spectral matching. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile organic solvents are vaporized in sealed vials and quantified via GC-FID using calibrated standards. |
| Moisture Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator. |
| Bromine Content | Oxygen Flask Combustion followed by Potentiometric Titration | Sample combusted in oxygen, bromine converted to bromide, then titrated with silver nitrate using potentiometric endpoint detection. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) | After acid digestion, elemental metals are atomized and excited in plasma; emission intensities are measured at characteristic wavelengths. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Inorganic residue determined by weighing sample before and after high-temperature ashing at 550-600 C. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as solid-to-liquid phase change under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against specified criteria under controlled lighting conditions. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation of anions on ion-exchange column; chloride quantified by conductivity response relative to calibration curve. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to calculate size distribution based on Mie theory. |
