Manufacturing Quality Control of 2,5-PYRIDINEDICARBOXYLIC ACID DIETHYL ESTER
| 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 under optimized chromatographic conditions. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of impurities using reversed-phase C18 column and UV absorbance at 254 nm. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) with FID | Volatile solvent residues are vaporized in sealed vials and quantified by GC-FID using external calibration. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of free carboxylic acid groups using standardized sodium hydroxide solution and potentiometric endpoint detection. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Comparison of sample solution color to platinum-cobalt standards; measured as APHA units at specified concentration and path length. |
| Appearance | Visual Inspection in Nessler tube | Assessment of clarity and presence of suspended particles or phase separation in a transparent, colorless solution. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Quantification of total heavy metals following acid digestion and measurement at characteristic wavelengths for lead. |
| Sulfated Ash | Gravimetric Analysis after high-temperature incineration | Residue mass remaining after combustion at 700-750 C in presence of sulfuric acid, expressed as weight percent. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separation of chloride anions on anion-exchange column and quantification via suppressed conductivity detection. |
| Melting Point | Capillary Melting Point Determination | Thermal transition observed as temperature range at which solid sample fully converts to liquid under controlled heating rate. |
| Refractive Index | Refractometry at 20 C | Measurement of light bending angle in sample relative to air, reported as nD20 value using calibrated digital refractometer. |
