Manufacturing Quality Control of 3,4-Dihydroxyphenylacetic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 280 nm, based on peak area comparison against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; impurities reported as area percent relative to total chromatographic area. |
| Residual Solvents | GC-FID | Detection and quantification of volatile organic solvents (e.g., methanol, ethyl acetate) by gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppb sensitivity. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content based on stoichiometric reaction with water. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash content after high-temperature incineration (700-800 C) and weighing of residual residue. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of pH in a 1% w/v aqueous suspension using calibrated glass electrode and pH meter. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement via controlled heating of sample in capillary tube; reported as onset and clear point. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light at 20 C using sodium D-line (589 nm); indicates chiral purity and identity. |
| Chloride Impurity | Ion Chromatography | Quantification of chloride ions using suppressed conductivity detection after anion exchange separation. |
| Sulfated Ash | Gravimetric Analysis | Determination of non-volatile inorganic residue after ignition with sulfuric acid pretreatment, followed by weighing. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic mesophilic microorganisms and detection of specified pathogens (e.g., E. coli) per pharmacopeial guidelines. |
