Manufacturing Quality Control of DIPHENYLCARBAZONE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 230-254 nm, comparing peak area to a certified reference standard. |
| Identity | FT-IR Spectroscopy | Confirmation by matching characteristic functional group absorption bands (e.g., C=O, C=C, aromatic C-H) to reference spectrum. |
| Melting Point | Capillary Melting Point Determination | Measurement of temperature range at which solid transitions to liquid, indicating crystalline purity and identity. |
| Loss on Drying | Gravimetric Analysis (105 C, 2 h) | Mass loss after drying under controlled temperature and time, reflecting volatile impurities and residual solvents. |
| Residue on Ignition | Sulfated Ash Method | Weight of inorganic residue remaining after high-temperature combustion, indicating inorganic impurities. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitation of sulfate as BaSO4 followed by weighing of dried precipitate. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after wet digestion, using lead as the toxicological marker and AAS detection. |
| Related Substances | HPLC-DAD | Separation and detection of structurally related impurities (e.g., phenyl maleic acid, unreacted benzaldehyde) using diode array detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with KF reagent to determine trace water based on stoichiometric iodine reaction. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determination of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to calculate size distribution of dry or dispersed particles. |
