Manufacturing Quality Control of 2,3-Dihydrobenzofuranyl-5-acetic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 220 nm. |
| Related Substances | HPLC-UV | Separation and detection of impurities using gradient elution and UV detection; identification and quantification relative to main peak. |
| Residual Solvents | GC-FID | Volatile organic solvents are separated by capillary GC and quantified using flame ionization detection with internal standard calibration. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric titration with iodine reagent; water reacts stoichiometrically with iodine and sulfur dioxide in pyridine-methanol medium. |
| Heavy Metals | ICP-MS | Elemental analysis after acid digestion; detection based on mass-to-charge ratio of metal ions with high sensitivity and multi-element capability. |
| Chloride Content | Ion Chromatography | Separation of anions on ion-exchange column followed by conductivity detection; quantification using chloride standard calibration. |
| Sulfated Ash | Gravimetric Analysis | Sample incinerated at 700-800 C, residue treated with sulfuric acid and re-ignited; ash weight expressed as percentage of original sample. |
| Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through solution; indicates enantiomeric purity and identity. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid; used for identity and purity assessment. |
| Residual Palladium | ICP-OES | After microwave-assisted acid digestion, palladium is quantified by optical emission intensity at characteristic wavelength. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity pattern to calculate particle size distribution based on Mie theory. |
| Microbial Limits | Membrane Filtration | Sample filtered through sterile membrane, then incubated on appropriate agar media; colony-forming units counted after incubation. |
