Manufacturing Quality Control of 5239-82-7
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based reagent. |
| Acidity (as H+) or Acid Value | Acid-Base Titration with NaOH | Neutralization of carboxylic acid groups using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measurement of non-volatile inorganic residue after controlled high-temperature combustion in a muffle furnace. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal impurities via absorption of characteristic wavelength light by ground-state atoms in a flame or graphite furnace. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions using anion-exchange column and suppressed conductivity detection. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile organic impurities are equilibrated in headspace vial and analyzed by GC-FID or GC-MS. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Comparison of sample solution color intensity to APHA platinum-cobalt standard scale using spectrophotometer or comparator. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range over which solid-to-liquid phase change occurs under controlled heating. |
| Specific Optical Rotation | Polarimetry | Measurement of angle of rotation of plane-polarized light caused by chiral molecules in solution at specified concentration and path length. |
| Non-Volatile Residue | Evaporation and Gravimetric Weighing | Determination of residue mass remaining after complete evaporation of a weighed sample under controlled conditions. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of structurally related impurities using reversed-phase C18 column and UV absorbance at 210 nm. |
