Manufacturing Quality Control of S-ETHYLISOTHIOUREA HYDROBROMIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with NaOH | Quantifies active ingredient by neutralizing the acidic HBr salt with standardized sodium hydroxide solution using potentiometric or visual endpoint detection. |
| Moisture Content | Karl Fischer Titration | Measures water content via stoichiometric reaction between water and Karl Fischer reagent (iodine, sulfur dioxide, base, and alcohol). |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by ignition at 500-600 C and weighing the residual non-volatile material. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Quantifies trace heavy metals after acid digestion by measuring elemental mass-to-charge ratios in an inductively coupled plasma mass spectrometer. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride ions by titration with silver nitrate using a silver indicator electrode to monitor AgCl precipitation endpoint. |
| Sulfate Impurity | Turbidimetric Method | Measures sulfate as barium sulfate precipitate formed upon addition of BaCl2 under controlled acidity; quantified by light scattering. |
| Related Substances | HPLC-UV | Separates and quantifies organic impurities using reversed-phase HPLC with UV detection at 210–230 nm based on retention time and peak area. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity via thermal behavior. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a defined aqueous solution (e.g., 1% w/v) using calibrated glass electrode pH meter. |
| Solubility in Water | Visual Observation and Filtration | Evaluates complete dissolution in specified volume of water at controlled temperature; assessed by clarity and absence of residue after filtration. |
| Bulk Density | Graduated Cylinder Method | Determines mass per unit volume by gently pouring sample into a calibrated cylinder and measuring settled volume. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dry powder particles by analyzing angular variation in laser light scattering intensity. |
