Manufacturing Quality Control of 5-Bromo-2,3-dihydro-1-benzofuran
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard under optimized chromatographic conditions. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of structurally similar impurities using reverse-phase chromatography and UV absorbance at 220-280 nm. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) with FID | Volatile organic solvents are vaporized in sealed vials and quantified by GC-FID using calibrated external standards. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine is generated in situ to react stoichiometrically with water; endpoint detected amperometrically. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Sample digested in acid matrix, then elemental emission intensities measured at characteristic wavelengths for quantitative metal analysis. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anions on ion-exchange column followed by quantitative detection via changes in solution conductivity. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample ignited at 700-800 C to volatilize organic matter; residual inorganic ash is weighed to determine non-volatile residue. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or optically as solid-to-liquid phase change under controlled heating rate. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution at specified concentration and path length. |
| Acid Value | Acid-Base Titration (NaOH standard solution) | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator; calculated as mg KOH per g sample. |
| Appearance (Color and Clarity) | Visual Inspection against Standard Solutions | Comparison of sample solution (in specified solvent) with reference standards (e.g., APHA color scale) under controlled lighting and viewing conditions. |
| Bulk Density | Tap Density Measurement (ASTM D1895) | Mass per unit volume determined after mechanical tapping of a known mass in a graduated cylinder to achieve reproducible packing. |
