Manufacturing Quality Control of 2,4-Dichlorobenzyl bromide
| 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 using a non-polar capillary column. |
| Related Substances | Gas Chromatography (GC) with FID or MS detection | Separation and semi-quantitative/quantitative detection of structurally related impurities using retention time and response factor matching. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile organic solvents are equilibrated in headspace vials and quantified by GC-FID against calibrated standards. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Acid Value | Acid-Base Titration (NaOH standard solution) | Neutralization of acidic impurities (e.g., HBr, HCl) with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Heavy Metals | ICP-OES after acid digestion | Sample digested in nitric/hydrochloric acid; total heavy metals (Pb, Cd, Hg, As, etc.) measured by plasma emission spectroscopy. |
| Chloride Content | Potentiometric Titration with AgNO3 | Precipitation of chloride ions as AgCl monitored by silver ion-selective electrode to determine endpoint. |
| Bromide Content | Ion Chromatography (IC) with conductivity detection | Separation of bromide anion on an anion-exchange column and quantification via suppressed conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature at which solid phase changes to liquid. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light and against standard references. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Sample ignited at 700-800 C; inorganic residue weighed after cooling in desiccator to determine non-volatile inorganic content. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral centers in solution at specified concentration and wavelength (589 nm). |
