Manufacturing Quality Control of 1,4-DIBROMO-2,3-BUTANEDIONE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area against calibrated standard. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on mass spectral fragmentation patterns and retention behavior. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water 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 trace metal elements (e.g., Pb, Cd, Hg, As) by atomic emission intensity at characteristic wavelengths. |
| Acid Value | Acid-Base Titration with NaOH | Measures acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color | Visual Comparison Against Hazen Scale | Evaluates sample color intensity by comparing to platinum-cobalt standard solutions under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects and quantifies volatile organic solvents (e.g., acetone, dichloromethane) by equilibrium vapor analysis. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to assess chiral purity and identity of stereoisomers. |
| Bulk Density | Graduated Cylinder Method | Determines mass per unit volume of freely settled powder under standardized conditions. |
