Manufacturing Quality Control of PRESSINOIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with NaOH | Quantifies pressinoic acid content by neutralizing with standardized sodium hydroxide solution using phenolphthalein or potentiometric endpoint detection. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric reaction between water and iodine generated in situ from KF reagent. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities by ignition at 700-800 C and weighing the residual ash. |
| Heavy Metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg, As) by plasma excitation and elemental emission spectroscopy. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 under controlled acidic conditions and determines mass after drying. |
| Related Substances | HPLC with UV Detection | Separates and quantifies structurally related impurities using reversed-phase C18 column and UV absorbance at 210 nm. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity in a 1% w/v aqueous solution using calibrated glass electrode. |
| Melting Point | Capillary Melting Point Apparatus | Identifies purity and identity by observing temperature range over which solid transitions to liquid. |
| Solubility Profile | Visual Observation in Standard Solvents | Evaluates dissolution behavior in water, ethanol, methanol, and ethyl acetate per USP/EP general chapter <781>. |
| Microbial Limits | Membrane Filtration and Culture | Detects aerobic microorganisms and absence of specified pathogens using validated filtration and incubation on nutrient media. |
