Manufacturing Quality Control of 1,7-DIOXASPIRO[5.5]UNDECANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via electrochemical reaction between iodine, sulfur dioxide, and water in methanol/pyridine medium. |
| Acid Value | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomic absorption of characteristic wavelengths after acid digestion. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions by silver nitrate titration monitored with silver electrode. |
| Color | Visual Comparison Against APHA Scale | Evaluates color intensity by matching sample solution to standardized platinum-cobalt color standards. |
| Refractive Index | Refractometry | Measures light bending angle at air-sample interface to infer purity and composition. |
| Specific Gravity | Pycnometry | Determines density relative to water at specified temperature using calibrated glass pycnometer. |
| Non-Volatile Residue | Evaporation and Gravimetry | Quantifies residue after solvent evaporation under controlled conditions and subsequent weighing. |
| Odor | Sensory Evaluation | Assesses off-odor presence by trained personnel per defined sensory protocol. |
| Appearance | Visual Inspection | Confirms clear, colorless to pale yellow liquid free from visible particulates or phase separation. |
