Manufacturing Quality Control of 3,4-DIBROMOSULFOLANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area relative to calibration standards. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on retention time and mass spectral fragmentation patterns. |
| 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 mode) | Determines water via electrochemical iodine generation and stoichiometric reaction with water. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Measures acidic impurities by titration with standardized sodium hydroxide using phenolphthalein indicator. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies metallic impurities (e.g., Pb, Cd, Hg, As) after acid digestion and plasma excitation. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride ions based on anion exchange and electrical conductivity response. |
| Sulfate Content | Ion Chromatography (IC) with conductivity detection | Separates and quantifies sulfate ions using anion exchange column and conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity. |
| Appearance | Visual Inspection in Standardized Lighting | Assesses physical state, color, and presence of particulates or phase separation against reference standards. |
| Bulk Density | Graduated Cylinder Method (ASTM D1895) | Measures mass per unit volume of freely settled powder under controlled conditions. |
| Loss on Drying (LOD) | Gravimetric Analysis after Oven Drying | Determines volatile content by weight loss upon heating at specified temperature and duration. |
