Manufacturing Quality Control of R-(-)-2-Butanol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantitative separation and detection based on volatility and retention time relative to a certified reference standard. |
| Optical Rotation | [alpha]D Measurement using Polarimeter | Measures the angle of rotation of plane-polarized light caused by chiral molecules in solution at specified concentration and path length. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Residue on Ignition | Gravimetric Analysis after Ignition | Sample is ignited at 700-800 C to volatilize organic matter; residual inorganic ash is weighed. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator. |
| Heavy Metals (as Pb) | Qualitative Sulfide Precipitation Test | Treatment with hydrogen sulfide under acidic conditions to form colored metal sulfide precipitates for visual comparison. |
| Chloride Content | Ion Chromatography (IC) | Separation of chloride anions on an ion-exchange column followed by conductivity detection. |
| Non-Volatile Residue | Evaporation and Gravimetry | Sample evaporated to dryness at 105 C; residue is weighed after cooling in desiccator. |
| Specific Gravity | Digital Density Meter | Measures density via oscillating U-tube principle and calculates specific gravity relative to water at specified temperature. |
| Refractive Index | Refractometry | Determines refractive index by measuring angle of light refraction at liquid-air interface using calibrated prism. |
| Appearance | Visual Inspection | Assessment of clarity and color against water-white standard in a clear glass container under controlled lighting. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation by GC followed by mass spectral identification and semi-quantitation of structurally related impurities. |
