Manufacturing Quality Control of ETHYL PHENYLPHOSPHINATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area against calibrated standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, and sulfur dioxide in pyridine/methanol medium. |
| Acidity (as H3PO4) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color | Visual Comparison or APHA Color Scale | Compares sample color to platinum-cobalt standard solutions under controlled lighting. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through sample to infer purity and composition. |
| Residue on Evaporation | Gravimetric Analysis | Weighs non-volatile residue after controlled evaporation of a known sample mass. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange and conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures absorbance of ground-state metal atoms atomized in flame or graphite furnace. |
| Phosphorus Content | UV-Vis Spectrophotometry after ammonium molybdate reduction | Forms phosphomolybdenum blue complex; absorbance measured at ~820 nm. |
| Residual Solvents | Gas Chromatography (GC) with Headspace Sampling | Quantifies volatile organic solvents by equilibrium partitioning into headspace gas phase. |
| Appearance | Visual Inspection | Assesses clarity and presence of particulates or immiscible phases in transparent container under white light. |
