| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 210 nm, comparing peak area to a certified reference standard. |
| Chiral Purity | Chiral HPLC | Separation of (R)- and (S)-enantiomers on a chiral stationary phase, with UV detection and enantiomeric excess calculation. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection, quantifying common solvents (e.g., methanol, ethyl acetate) against calibration standards. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine reagent to determine trace water based on stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Ni) after acid digestion, using mass spectrometric detection. |
| Residual Palladium | ICP-OES | Quantification of palladium catalyst residue after microwave-assisted acid digestion, via atomic emission spectroscopy. |
| Acid Value | Acid-Base Titration | Neutralization of free carboxylic acid groups with standardized NaOH solution using phenolphthalein indicator. |
| Appearance | Visual Inspection | Comparison of sample color and clarity against water-white standard under controlled white light and specified viewing conditions. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition determination by observing solid-to-liquid phase change in a capillary tube under controlled heating rate. |
| Loss on Drying | Gravimetric Analysis | Mass loss measurement after drying under vacuum at 60 C for 2 hours, expressed as weight percent. |
| Related Substances | HPLC-UV | Detection and quantification of structurally related impurities using gradient HPLC with UV detection at multiple wavelengths. |
