Manufacturing Quality Control of Benzene,1,3-dibroMo-5-ethyl-
| 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 detection | Separation and quantification of impurities (e.g., mono-bromo, tri-bromo, and ethylbenzene derivatives) relative to main peak area. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile organic solvents (e.g., toluene, dichloromethane) are extracted into headspace and quantified via calibrated GC-FID. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acid Value | Acid-Base Titration (NaOH in methanol) | Neutralization of acidic impurities (e.g., HBr) with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element quantification after acid digestion; detection based on element-specific atomic emission lines. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of chloride anions on an anion-exchange column followed by quantitative detection via suppressed conductivity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the solid transforms to liquid over a defined temperature range. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against a white background under controlled lighting conditions. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Mass difference measured before and after high-temperature ashing to determine inorganic residue content. |
| Specific Gravity | Digital Density Meter | Density determined from oscillating U-tube principle using calibrated instrument at specified temperature (e.g., 20 C). |
| Refractive Index | Abbe Refractometer | Measurement of light refraction angle at air-sample interface to calculate refractive index at specified wavelength (e.g., 589 nm) and temperature. |
