Manufacturing Quality Control of Diethyl pyridine-3,5-dicarboxylate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and detection of impurities (e.g., monoethyl ester, free acid, unreacted pyridine) relative to main peak using gradient elution. |
| Residual Solvents | GC-FID | Identification and quantification of residual ethanol, ethyl acetate, or toluene based on retention time and flame ionization response. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine reagent where water reacts stoichiometrically to determine trace moisture content. |
| Acid Value | Acid-Base Titration | Neutralization of free carboxylic acid groups with standardized KOH solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Measurement of yellowness intensity by matching sample color to APHA platinum-cobalt standard solutions or absorbance at 430 nm. |
| Density at 20 C | Digital Density Meter | Determination of mass per unit volume using oscillating U-tube principle calibrated with water and air. |
| Refractive Index at 20 C | Refractometry | Measurement of light bending angle through the sample using a calibrated Abbe refractometer. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion, based on characteristic atomic emission wavelengths. |
| Chloride Content | Ion Chromatography | Separation and conductivity detection of chloride anions following aqueous extraction and filtration. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile inorganic residue remaining after high-temperature ashing at 700 C. |
