| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at ~254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-DAD or UPLC-MS | Separation and identification/quantification of structurally related impurities (e.g., hydrolysis products, starting materials) using gradient elution and spectral or mass confirmation. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify low-boiling organic solvents (e.g., methanol, ethyl acetate, toluene) per ICH Q3C guidelines. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic elements (Pb, Cd, Hg, As) after acid digestion, achieving sub-pptr detection limits. |
| Moisture Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water content via iodine generation and stoichiometric reaction with water in anhydrous medium. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid–liquid phase transition temperature using calibrated capillary apparatus per USP <741>. |
| Specific Optical Rotation | [α]D | Measurement of plane-polarized light rotation in solution using a digital polarimeter at 20 °C and sodium D-line (589 nm). |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Ignition at 700–800 °C followed by weighing of inorganic residue to assess inorganic impurities. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | pH determination of a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode per USP <791>. |
