Manufacturing Quality Control of 1,4-DIBROMO-2,3-BIS(BROMOMETHYL)-2-BUTENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | 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 followed by GC separation. |
| Water Content | Karl Fischer Titration (Coulometric) | Determines trace water via electrochemical iodine generation and stoichiometric reaction with water. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Measures acidic impurities by neutralization with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Halogen Content (Total Bromine) | Oxygen Flask Combustion followed by Potentiometric Titration | Organic bromine is converted to bromide ion by combustion in oxygen, then titrated with silver nitrate. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) | Quantifies trace metals after acid digestion by measuring element-specific atomic emission intensities. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of particulates or phase separation under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separates and quantifies chloride ions based on anion exchange retention and conductivity response. |
| Density | Digital Density Meter | Determines mass per unit volume at specified temperature using oscillating U-tube principle. |
