Manufacturing Quality Control of 14307-43-8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (NH4)2C4H4O6 | Acid-Base Titration | Direct titration with standardized NaOH after dissolution and heating to decompose ammonium salt; endpoint detected potentiometrically or with phenolphthalein. |
| Loss on Drying | Gravimetric (Thermogravimetry) | Mass loss measured after drying at 105 C for 2 hours under controlled humidity and airflow. |
| Heavy Metals (as Pb) | Colorimetric Sulfide Precipitation | Reaction with thioacetamide in buffered acidic medium to form colored metal sulfide complexes, compared visually or spectrophotometrically against lead standard. |
| Chloride | Potentiometric Titration | Titration with silver nitrate using silver indicator electrode; chloride forms insoluble AgCl precipitate, causing potential jump at endpoint. |
| Sulfate | Gravimetric (Barium Sulfate Precipitation) | Precipitation as BaSO4 in acidic medium followed by filtration, ignition, and weighing of residue. |
| Iron (Fe) | UV-Vis Spectrophotometry | Formation of orange-red Fe(II)-1,10-phenanthroline complex at pH 3–4; absorbance measured at 510 nm. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Measurement using calibrated glass electrode in a 1% w/v aqueous solution at 25 C. |
| Residue on Ignition | Gravimetric (Ignition Loss) | Mass of non-volatile residue after ignition at 700 C for 30 minutes in platinum crucible. |
| Ammonia Content | Kjeldahl Nitrogen Determination | Digestion with concentrated H2SO4 and catalyst, distillation of liberated NH3 into boric acid, followed by titration with standardized HCl. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a 10% w/v solution in water at 20 C using sodium D-line. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles in liquid medium to determine volume-based size distribution. |
| Water Content | Karl Fischer Titration | Volumetric titration with Karl Fischer reagent (I2, SO2, pyridine, methanol); based on stoichiometric reaction with water. |
