Manufacturing Quality Control of 77377-52-7
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by separation on capillary column and flame ionization detection relative to external standard. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Detects volatile organic impurities via headspace equilibration followed by GC-FID analysis using calibrated standards. |
| Water Content | Karl Fischer Titration (Coulometric) | Determines trace water by electrochemical generation of iodine reacting stoichiometrically with water in anhydrous medium. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Measures acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis after high-temperature ashing | Quantifies non-volatile inorganic residue by weighing sample before and after ignition at 700-800 C. |
| Heavy Metals | ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) | Simultaneously detects multiple metallic impurities based on element-specific atomic emission intensities in plasma. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Appearance | Visual Inspection against standard white background | Assesses physical state, color, and clarity by direct observation under controlled lighting conditions. |
| Specific Gravity | Digital Density Meter measurement | Determines density relative to water at specified temperature using oscillating U-tube principle. |
| Refractive Index | Abbe Refractometer measurement | Measures bending of light at air-sample interface to determine refractive index at specified wavelength and temperature. |
| Optical Rotation | Polarimetry | Detects chiral impurities or enantiomeric excess by measuring rotation of plane-polarized light through a solution. |
| Volatile Impurities Profile | GC-MS (Gas Chromatography-Mass Spectrometry) | Identifies and semi-quantifies unknown volatile impurities via retention time and mass spectral library matching. |
