Manufacturing Quality Control of 3,5,6-Trichloro-2-pyridinol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 220-254 nm, based on peak area comparison against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., dichloro and tetrachloro analogues) using gradient HPLC-UV; identification by retention time matching and/or spiked standards. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile solvents (e.g., methanol, acetone, toluene) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, Cr, and Ni after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppb sensitivity. |
| Chloride Ion (Inorganic Chloride) | Ion Chromatography | Separation and conductivity detection of Cl- anions in aqueous extract; distinguishes ionic chloride from covalently bound chlorine. |
| Residue on Ignition | Gravimetric Analysis | Determination of non-volatile inorganic residue after high-temperature ashing (500-600 C) and weighing of the cooled crucible. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement using calibrated capillary apparatus; identifies purity and identity based on sharpness and temperature range. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using light scattering principles to determine D10, D50, D90 values per ISO 13320. |
| Bulk Density | ASTM D1895 | Measurement of mass per unit volume for freely settled powder in a standardized cylinder under controlled conditions. |
| pH of Aqueous Suspension | pH Meter | Determination of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode; indicates acidic/basic impurity profile. |
| Organic Volatile Impurities (OVI) | GC-MS | Targeted and untargeted screening of low-level volatile organic impurities using gas chromatography coupled with mass spectrometry for identification and quantification. |
