Manufacturing Quality Control of 1,4-Dibromopentane
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 1,4-dibromopentane peak area relative to calibration standards using flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine generated in situ reacting stoichiometrically with water. |
| Acidity (as HBr) | Acid-Base Titration with NaOH | Neutralizes acidic impurities (e.g., HBr) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates a known sample mass under controlled conditions and weighs non-volatile residue. |
| Color | Visual Comparison to Hazen (APHA) Scale | Compares sample color against platinum-cobalt standard solutions in a Nessler tube under controlled lighting. |
| Density at 20 degC | Digital Density Meter | Determines density by measuring oscillation period of a U-tube filled with sample at controlled temperature. |
| Refractive Index at 20 degC | Refractometry | Measures angle of light refraction through sample using a calibrated prism-based instrument. |
| Boiling Range | Distillation (ASTM D1078) | Determines initial and final boiling points using a micro-distillation apparatus under specified pressure. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies trace heavy metals after wet digestion and extraction, based on absorption of element-specific wavelengths. |
| Non-Volatile Residue | Gravimetric Analysis | Heats evaporated residue to constant weight after solvent removal to determine inorganic/organic ash content. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Residual Solvents (e.g., Hexane, Ethanol) | Gas Chromatography (GC) with FID | Identifies and quantifies volatile solvents by retention time and peak area against certified standards. |
