Manufacturing Quality Control of 2,5-Dibromoterephthalic acid diethyl ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., mono-brominated analogues, unreacted diethyl terephthalate, hydrolysis products) using gradient elution and UV detection. |
| Residual Solvents (Ethanol, Ethyl Acetate) | GC-FID | Separates and quantifies volatile organic solvents by gas chromatography with flame ionization detection using internal standard calibration. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Measures trace heavy metal concentrations after acid digestion via inductively coupled plasma mass spectrometry with isotope-dilution or external calibration. |
| Moisture Content | Karl Fischer Titration | Determines water content electrochemically by iodine titration in anhydrous methanol-based solvent system. |
| Acid Value | Acid-Base Titration | Measures free carboxylic acid groups (if present due to ester hydrolysis) by titration with standardized NaOH solution using phenolphthalein indicator. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, reflecting crystallinity and purity per pharmacopeial/industrial standards. |
| Residue on Ignition | Gravimetric Analysis | Quantifies inorganic ash content after high-temperature combustion (700–800 °C) and weighing of residual residue. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions (from side reactions or reagent carryover) using suppressed conductivity detection. |
| Appearance (Color & Clarity) | Visual Inspection | Assesses physical state, color (white to off-white), and absence of visible particulates or cloudiness in solution (e.g., 5% w/v in acetone). |
