Manufacturing Quality Control of 5-BROMO-4-CHLORO-6-METHYLPYRIMIDINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Related Substances (Impurities) | HPLC-UV or UPLC-MS | Separation and quantification of structurally related impurities (e.g., isomers, hydrolysis/degradation products) using gradient elution and UV or mass-selective detection. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, acetone, dichloromethane) per ICH Q3C guidelines. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification of trace heavy metals after acid digestion, leveraging high sensitivity and isotopic resolution of inductively coupled plasma mass spectrometry. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water content via iodine generation and stoichiometric reaction with water in anhydrous methanol-based medium. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing the temperature range over which solid-to-liquid phase change occurs under controlled heating. |
| Chloride Content (Inorganic Chloride) | Ion Chromatography (IC) with Conductivity Detection | Separation and quantification of chloride ions in aqueous extract using anion-exchange column and suppressed conductivity detection. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Analysis | Determination of non-volatile inorganic residue after controlled charring and sulfuric acid treatment followed by high-temperature ignition and weighing. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using Mie scattering theory to determine volume-based particle size distribution. |
| Specific Optical Rotation | [α]D Measurement (Polarimetry) | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution at 589 nm (Na D-line), indicating enantiomeric purity if applicable. |
| pH of Aqueous Suspension | pH Meter | Determination of surface acidity/basicity by measuring hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Bulk & Tapped Density | ASTM D6393 (Powder Rheology Tester) | Gravimetric determination of mass per unit volume before and after standardized mechanical tapping to assess flowability and compressibility. |
| Microbial Limits | Membrane Filtration + TSA/SDA Culture | Enumeration of aerobic bacteria, yeasts, and molds after filtration, membrane transfer to tryptic soy agar and sabouraud dextrose agar, and incubation per USP <61>. |
