Manufacturing Quality Control of 4526-07-2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration curve using flame ionization detection. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatiles are equilibrated in headspace vial and quantified by GC-FID or GC-MS. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous medium. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomization and excitation of metals in plasma; emission intensity correlates with concentration. |
| Chloride Impurity | Ion Chromatography (IC) | Separation of anions on ion-exchange column followed by conductivity detection. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein endpoint. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample ignited at 700-800 C; residue mass measured after cooling in desiccator. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against specified reference under controlled lighting. |
| Melting Point | Capillary Melting Point Determination | Temperature range at which solid transitions to liquid observed using calibrated melting point apparatus. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light caused by chiral impurities or degradation products. |
| Volatile Impurities (Non-solvent) | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation and identification of low-boiling impurities via retention time and mass spectral matching. |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Analysis of scattered laser light intensity pattern to determine size distribution of suspended particles. |
