Manufacturing Quality Control of 4-Bromo-1-butanol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 4-bromo-1-butanol peak area relative to a calibrated standard using retention time and response factor. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acidity (as HBr) | Acid-Base Titration with NaOH | Neutralizes acidic impurities (e.g., residual HBr) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after high-temperature ashing and weighing of the cooled crucible. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomizing the sample and measuring absorption of characteristic wavelength light. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange retention and conductivity detection. |
| Color | Visual Comparison against Hazen Scale | Compares sample color in a Nessler tube to platinum-cobalt standard solutions under controlled lighting. |
| Density | Digital Density Meter | Measures mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determines refractive index by measuring angle of light refraction at air-sample interface at 20 C. |
| Volatility Residue | Gravimetric Analysis after Evaporation | Weighs non-volatile residue remaining after controlled evaporation of a fixed sample volume at 105 C. |
| Aldehyde Impurity | UV-Vis Spectrophotometry after derivatization | Quantifies aldehydes via absorbance of chromophore formed from reaction with 2,4-dinitrophenylhydrazine. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects and quantifies volatile organic solvents by analyzing equilibrium vapor phase above heated sample. |
