Manufacturing Quality Control of 2,3-Diaminobenzoic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration based on the reaction of water with iodine and sulfur dioxide in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C to volatilize organic matter, then weighing inorganic residue after cooling in desiccator. |
| Heavy Metals (as Pb) | Colorimetric Limit Test with Thioglycolic Acid | Reaction of heavy metal ions with thioglycolic acid under controlled pH to form colored complexes, compared visually to lead standard. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions using anion-exchange column with conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitation of sulfate as BaSO4 in acidic medium, followed by filtration, drying, and weighing. |
| Related Substances | HPLC-DAD | Detection and semi-quantification of structurally related impurities using HPLC with diode array detection across 200-400 nm. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range over which solid transforms to liquid, measured using calibrated capillary apparatus. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity in saturated aqueous suspension using calibrated glass electrode and pH meter. |
| Iron (Fe) Content | Atomic Absorption Spectroscopy (AAS) | Quantification of iron via absorption of specific wavelength light (248.3 nm) by ground-state Fe atoms in flame. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Measurement of mass loss upon heating to 105 C for 2 hours under air, reflecting volatile content including residual solvents. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separation and quantification of residual solvents using capillary GC column with flame ionization detection. |
