Manufacturing Quality Control of Probenecid sodium
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Piroxicam Sodium Content) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification and control based on relative retention times and threshold limits. |
| Loss on Drying | Gravimetric (105 C drying) | Mass loss measured after drying sample at 105 C to constant weight, indicating volatile content including residual solvents and moisture. |
| Residual Solvents | GC-FID | Quantitative analysis of specified organic solvents (e.g., methanol, acetone) using gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-OES | Multi-element detection of heavy metals (Pb, Cd, As, Hg, Ni) after acid digestion, based on atomic emission intensity at characteristic wavelengths. |
| Chloride Impurity | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Sulfate Impurity | Turbidimetric Method | Formation of barium sulfate precipitate in acidic medium; quantification via measurement of turbidity at 420 nm. |
| pH (1% aqueous solution) | pH Meter Measurement | Direct measurement of hydrogen ion activity in a 1% w/v aqueous solution using calibrated pH electrode. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light at 20 C using sodium D-line (589 nm), indicating chiral purity and identity. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent; water reacts stoichiometrically to determine absolute moisture content. |
| Microbial Limits | Membrane Filtration and Plate Count | Enumeration of aerobic bacteria, yeasts, and molds after filtration, membrane transfer to selective agar media, and incubation per pharmacopeial guidelines. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to calculate volume-based particle size distribution in dry or dispersed state. |
