Manufacturing Quality Control of 3,4'-OXYDIANILINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Moisture Content | Karl Fischer Titration | Volumetric titration based on the stoichiometric reaction of water with iodine and sulfur dioxide in pyridine/methanol medium. |
| Melting Point | Capillary Melting Point Determination | Measurement of temperature range at which solid transitions to liquid, using calibrated capillary apparatus per USP <741>. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Heating sample at 700-800 C to constant weight and calculating inorganic residue as percentage of original mass. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions using anion-exchange column and suppressed conductivity detection. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element detection after acid digestion; quantification by emission intensity at characteristic wavelengths (e.g., Pb 220.353 nm). |
| Iron Content | AAS (Flame Atomic Absorption Spectroscopy) | Atomization of digested sample in air-acetylene flame and measurement of absorption at 248.3 nm. |
| Related Substances | HPLC-DAD | Identification and quantification of impurities via retention time matching and spectral comparison using diode-array detection. |
| Solvent Residues (e.g., DMF, THF) | GC-FID | Separation by capillary GC column and detection via flame ionization for residual polar solvents. |
| pH of Aqueous Suspension | Potentiometric Measurement | Determination using calibrated pH electrode in 1% w/v aqueous suspension per EP 2.2.3. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity pattern to calculate volume-based particle size distribution. |
| Bulk Density | ASTM D1895 Method A | Measurement of mass per unit volume of freely settled powder in a standardized cylinder. |
