Manufacturing Quality Control of 4-Ethoxy-3-nitropyridine hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-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 relative to reference standards or threshold limits. |
| Residual Solvents | GC-FID | Detection and quantification of volatile organic solvents by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent to determine water content based on stoichiometric reaction with water. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion, using inductively coupled plasma optical emission spectrometry. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| pH of Aqueous Solution | pH Meter Measurement | Direct measurement of pH in a defined aqueous suspension or solution using calibrated pH electrode and buffer standards. |
| Loss on Drying | Gravimetric Method | Weight loss measured after drying sample at specified temperature (e.g., 105 C) under vacuum or air until constant weight is achieved. |
| Residue on Ignition | Gravimetric Method | Mass of non-volatile inorganic residue determined after high-temperature ashing (e.g., 600 C) of the sample in a platinum crucible. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to calculate particle size distribution based on Mie theory. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, observed visually in capillary tube under controlled heating rate. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating chiral purity and identity confirmation. |
