Manufacturing Quality Control of 4-Chloro-3-methylpyridine hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and peak area normalization. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, acetone, ethyl acetate) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content in the sample. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion and dilution. |
| Chloride Ion Content | Potentiometric Titration | Titration with silver nitrate using silver indicator electrode to determine free chloride from hydrolysis or residual HCl. |
| pH of Aqueous Solution | pH Meter Measurement | Direct measurement of pH in a 1% w/v aqueous suspension using calibrated pH meter with glass electrode. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Loss on Drying | Gravimetric Method | Weight loss measured after drying sample at 105 C for 2 hours under controlled atmosphere. |
| Residue on Ignition | Sulfated Ash Method | Mass of non-volatile inorganic residue after high-temperature ignition (700–800 C) following sulfuric acid treatment. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser diffraction to determine D10, D50, D90 values. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic mesophilic bacteria and molds/yeasts per USP <61> using membrane filtration and selective agar media. |
