Manufacturing Quality Control of 62893-24-7
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Piperacillin Acid Content) | Acid-Base Titration with NaOH | Quantifies active ingredient via neutralization of carboxylic acid groups using standardized sodium hydroxide solution. |
| Related Substances | HPLC with UV Detection | Separates and quantifies impurities based on retention time and UV absorbance at 210–254 nm. |
| Water Content | Karl Fischer Titration | Measures water by electrochemical reaction between iodine, sulfur dioxide, and water in methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weighing of residual residue. |
| Heavy Metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg) via atomic emission spectroscopy after acid digestion. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride ions by silver nitrate titration monitored with silver indicator electrode. |
| Sulfate Impurity | Turbidimetric Method | Measures sulfate as barium sulfate precipitate formed in acidic medium, quantified by light scattering. |
| pH of Aqueous Solution | pH Potentiometry | Determines hydrogen ion activity using calibrated glass electrode in a saturated aqueous suspension. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution by measuring angular variation in intensity of laser light scattered by dispersed particles. |
| Microbial Contamination | Membrane Filtration and Plate Count | Detects viable aerobic microorganisms by filtration, membrane transfer to agar media, and colony enumeration. |
| Crystal Form | X-Ray Powder Diffraction (XRPD) | Identifies polymorphic form by comparing diffraction pattern against reference standards using Bragg’s law. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents based on volatility and flame ionization detection response. |
