Manufacturing Quality Control of 4,7-DIMETHYL-1H-INDENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 4,7-dimethylindene content by retention time and peak area comparison against a certified reference standard. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration based on the stoichiometric reaction of iodine with water in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities by weighing residue after high-temperature ashing at 700-800 C. |
| Acid Value | Acid-Base Titration with NaOH | Quantifies acidic impurities via titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness intensity by matching sample color to APHA platinum-cobalt standard solutions or measuring absorbance at 455 nm. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle calibrated with water and air. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through the sample using Abbe refractometer calibrated with distilled water. |
| Non-Volatile Residue | Evaporation and Gravimetry | Quantifies volatile loss by evaporating known mass under controlled conditions and weighing residual material. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Detects total heavy metals after wet digestion by measuring atomic absorption at characteristic wavelengths. |
| Chlorinated Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies chlorinated organic impurities using retention time and mass spectral fragmentation patterns. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic sulfate content after sulfuric acid treatment and ignition to constant weight. |
| Odor | Organoleptic Assessment | Evaluates off-odor presence and intensity by trained personnel under standardized conditions. |
