| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Acid Chloride Content | Acid-Base Titration with Potentiometric Endpoint | Hydrolysis of acid chloride to carboxylic acid followed by titration with standardized NaOH solution; endpoint detected by pH change. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile solvents are vaporized in sealed vials and quantified via GC-FID using calibrated standard solutions. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical titration where iodine is generated in situ to react stoichiometrically with water; endpoint determined coulometrically. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Sample digested in acid matrix, then elemental emission intensities measured at characteristic wavelengths for quantitative metal analysis. |
| Chloride Ion Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation of anions on an ion-exchange column followed by quantitative detection based on electrical conductivity of eluted chloride ions. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation on reversed-phase C18 column; impurities detected at 254 nm and quantified relative to main peak using external standard calibration. |
| Appearance | Visual Inspection in Glass Vial Against White/Black Background | Assessment of physical state, color, and clarity under controlled lighting conditions per USP <941>. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, using calibrated digital melting point instrument. |
| Residue on Ignition | Gravimetric Analysis after High-Temperature Ashing | Sample ignited at 700-800 C; residue weighed after cooling in desiccator to determine inorganic ash content. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution in a standardized cell at specified concentration and wavelength (589 nm). |
| pH of Aqueous Solution | Potentiometric pH Measurement | pH measured using calibrated glass electrode in saturated aqueous suspension prepared per ICH Q5C guidance. |
