Manufacturing Quality Control of 3-Oxocyclopentanecarboxylic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 210 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., acetone, ethyl acetate, methanol) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation in pyridine-methanol solvent system to determine trace water content. |
| Heavy Metals | ICP-MS | Inductively coupled plasma mass spectrometry for simultaneous quantification of toxic elements (e.g., Pb, Cd, Hg, As) at sub-pptr levels. |
| Chloride Content | Ion Chromatography | Separation and conductivity detection of chloride ions after aqueous extraction and filtration. |
| Sulfated Ash | Gravimetric Analysis | Ignition at 700-750 C followed by weighing of residual inorganic sulfate ash after treatment with sulfuric acid. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid-to-liquid phase transition occurs, indicating crystallinity and purity. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Electrode-based measurement of hydrogen ion activity in a saturated aqueous suspension or dilute solution. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light against standard reference. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample to determine volume-weighted particle size distribution (D10, D50, D90). |
