Manufacturing Quality Control of 2-Butene-1,4-diyl bis(bromoacetate)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 220 nm. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using gradient HPLC with diode-array detection; relative retention times and UV spectra support structural assignment. |
| Residual Solvents | GC-FID | Quantitative determination of volatile organic solvents (e.g., acetone, dichloromethane) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water; endpoint detected amperometrically. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator or potentiometric endpoint detection. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion; detection based on characteristic atomic emission lines following plasma excitation. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection; chloride quantified via calibration curve. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature at which solid-to-liquid phase change occurs under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against specified criteria (e.g., white to off-white crystalline powder, free from visible particulates). |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after drying under specified temperature and vacuum conditions; reflects volatile content including moisture and residual solvents. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light by chiral molecules in solution; reported as degrees per dm·g/mL at specified wavelength and temperature. |
| Residue on Ignition | Gravimetric Ashing | Mass of non-volatile inorganic residue determined after high-temperature incineration of sample in a platinum crucible. |
