Manufacturing Quality Control of 4-Aminophenylacetic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (p-Aminophenylacetic Acid) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against a certified reference standard. |
| Appearance | Visual Inspection | Assessment of physical state and color by observation under controlled lighting against established visual standards for white to off-white crystalline powder. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating purity via depression or broadening relative to literature value (187-191 C). |
| Loss on Drying | Gravimetric (Oven Drying) | Measurement of mass loss after drying at 105 C for 2 hours, reflecting volatile impurities and residual solvents. |
| Residue on Ignition | Sulfated Ash (Gravimetric) | Quantification of inorganic residue after high-temperature incineration (~700 C), indicating inorganic impurity content. |
| Chloride Impurity | Potentiometric Titration (AgNO3) | Titration with silver nitrate using a silver electrode; endpoint detected by potential change due to AgCl precipitation. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy measuring absorbance of characteristic wavelengths after acid digestion and matrix matching. |
| Related Substances | HPLC-DAD | Separation and detection of structurally related impurities (e.g., p-phenylenediamine, benzoic acid) using gradient HPLC with diode array detection. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric titration with iodine-based reagent; quantifies water via stoichiometric reaction with iodine and sulfur dioxide. |
| pH of Aqueous Solution | pH Meter | Measurement of hydrogen ion activity in a 1% w/v aqueous suspension using calibrated pH electrode. |
| Iron (Fe) | ICP-OES | Inductively coupled plasma optical emission spectrometry detecting Fe-specific emission lines after microwave-assisted acid digestion. |
| Sulfated Ash Limit | Gravimetric (Sulfated Ash) | Determination of non-volatile inorganic residue after sulfuric acid treatment and ignition, per USP/EP general chapter. |
