Manufacturing Quality Control of 72185-81-0
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 210 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of impurities using gradient HPLC-UV; identification and quantification against reference standards or threshold limits. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, ethyl acetate) based on retention time and calibration curves. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Heavy Metals | ICP-OES | Multi-element detection after acid digestion; quantifies metals (e.g., Pb, Cd, Ni) by atomic emission at characteristic wavelengths. |
| Optical Rotation | [alpha]D Measurement | Determination of specific optical rotation using a polarimeter at 20 C and sodium D-line (589 nm) to confirm stereochemical integrity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal analysis by gradual heating of solid sample; endpoint determined by complete disappearance of crystalline structure. |
| pH (1% w/v aqueous solution) | pH Meter | Electrochemical measurement of hydrogen ion activity in a standardized aqueous solution at 25 C. |
| Loss on Drying (LOD) | Gravimetric Thermogravimetry | Mass loss measured after drying under controlled temperature and vacuum or nitrogen purge. |
| Residue on Ignition | Gravimetric Ashing | Weight of inorganic residue remaining after high-temperature combustion of sample in a muffle furnace. |
| Microbial Limits | Membrane Filtration & Culture | Enumeration of aerobic bacteria, yeasts, and molds using filtration, membrane transfer to selective agar media, and incubation per USP <61>. |
