Manufacturing Quality Control of 3,4-Dichlorophenylhydrazine hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., methanol, acetone) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion and plasma excitation. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using silver indicator electrode; endpoint detected by potential inflection corresponding to AgCl precipitation. |
| pH of Aqueous Solution | pH Meter Measurement | Direct measurement of pH in a 1% w/v aqueous suspension using calibrated glass electrode pH meter. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, observed visually under controlled heating rate. |
| Loss on Drying | Gravimetric Method | Weight loss measured after drying sample at 105 C for 2 hours under vacuum or forced-air oven. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to calculate volume-based particle size distribution in dispersed dry powder. |
| Organic Volatile Impurities (OVI) | GC-MS | Targeted and non-targeted screening of volatile impurities using gas chromatography coupled with mass spectrometry detection. |
| Residue on Ignition | Gravimetric Ashing | Measurement of inorganic residue remaining after high-temperature incineration (600–700 C) followed by cooling and weighing. |
