Manufacturing Quality Control of 2,4-Dichloro-5-aminopyrimidine
| 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-DAD | Separation and identification of impurities using HPLC coupled with diode array detection; impurities quantified relative to main peak using response factors. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common organic solvents (e.g., methanol, acetone, DMF) based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element analysis after acid digestion; quantification of heavy metals by measuring atomic emission intensities at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of chloride ions on an anion-exchange column with suppressed conductivity detection; quantified using chloride calibration standards. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement using controlled heating rate; onset and range determined visually or automatically. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under standardized lighting and against white/black backgrounds. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing (600-800 C) to determine inorganic non-volatile impurities. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode after equilibration. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as function of angle to derive volume-based particle size distribution in dispersed sample. |
| Bulk Density | Tap Density Tester | Determination of mass per unit volume after mechanical tapping of powder in a graduated cylinder according to USP <616>. |
