| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (purity) | Acid-base titration with standardized NaOH | Quantifies total basic nitrogen content by neutralizing free amine groups with standard alkali solution. |
| Specific optical rotation | [alpha]D measurement using polarimeter | Measures the degree of rotation of plane-polarized light to confirm enantiomeric identity and purity. |
| Water content | Karl Fischer titration | Determines water by coulometric or volumetric reaction between iodine, sulfur dioxide, and water in methanol/pyridine medium. |
| Residue on ignition | Gravimetric analysis after high-temperature ashing | Measures non-volatile inorganic impurities remaining after combustion at 700-800 C. |
| Heavy metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, Ni) by atomic emission spectroscopy following acid digestion. |
| Chloride content | Potentiometric titration with AgNO3 | Determines chloride ions via silver nitrate titration monitored by silver electrode potential change. |
| Related substances | HPLC with UV detection | Separates and quantifies structurally similar impurities using reversed-phase chromatography and UV absorbance. |
| Residual solvents | GC-FID | Identifies and quantifies volatile organic solvents (e.g., methanol, acetone) by gas chromatography with flame ionization detection. |
| pH of aqueous solution | Potentiometric pH measurement | Measures hydrogen ion activity in a defined aqueous solution using calibrated pH electrode. |
| Melting point | Capillary melting point apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity. |
| Appearance | Visual inspection against standard | Evaluates physical state, color, and presence of foreign particles under controlled lighting conditions. |
| Bulk density | Graduated cylinder method (ASTM D1895) | Measures mass per unit volume of freely settled powder using standardized cylinder and weighing procedure. |
