Manufacturing Quality Control of 1-BROMO-3-ETHYNYL-BENZENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration curve using volatile organic separation and flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by high-temperature ashing followed by weighing of residual mass. |
| Heavy Metals | ICP-OES | Quantifies trace metal elements (e.g., Pb, Cd, Hg) by plasma excitation and elemental emission wavelength detection. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange retention and conductivity detection. |
| Acidity (as HBr) | Acid-Base Titration | Neutralizes acidic impurities with standardized NaOH solution using phenolphthalein endpoint detection. |
| Color | Visual Comparison Against APHA Scale | Evaluates sample color intensity by matching against platinum-cobalt standard solutions under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects and quantifies volatile solvents (e.g., acetone, toluene) via equilibrium vapor phase analysis. |
| Appearance | Visual Inspection | Assesses physical state, clarity, and presence of particulates or phase separation in a clear glass container under white light. |
| Specific Optical Rotation | Polarimetry | Measures rotation angle of plane-polarized light caused by chiral impurities or enantiomeric excess in solution. |
| Bulk Density | Graduated Cylinder Method | Determines mass per unit volume by gently pouring material into calibrated cylinder and measuring settled volume. |
