Manufacturing Quality Control of 3,4-Diaminobenzonitrile
| 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 or coulometric titration based on the stoichiometric reaction of water with iodine, sulfur dioxide, and base in methanol/pyridine medium. |
| Residual Solvents | GC-FID | Separation and quantification of volatile organic solvents (e.g., DMF, toluene) using capillary gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and others after acid digestion, based on element-specific atomic emission intensities. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride anions using anion-exchange column and suppressed conductivity detector. |
| Sulfate Impurity | Gravimetric Analysis | Precipitation of sulfate as barium sulfate followed by filtration, drying, and weighing of the precipitate. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using calibrated capillary apparatus under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of visible particulates or discoloration against established reference standards under controlled lighting. |
| Particle Size Distribution | Laser Diffraction | Measurement of particle size distribution based on angular variation in intensity of laser light scattered by dispersed particles in air or liquid. |
| Related Substances | HPLC-DAD | Identification and quantification of structurally related impurities (e.g., mono-amino analogs, oxidation products) using diode array detection and retention time matching. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode pH meter. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Determination of volatile content by measuring mass loss upon controlled heating (e.g., 105 C for 2 h) under nitrogen or air atmosphere. |
