Manufacturing Quality Control of 1,2-TRIMETHYLENEDIOXYBENZENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area relative to calibrated standard. |
| Related Substances | Gas Chromatography (GC) with FID or MS detection | Separates and detects impurities based on volatility and retention behavior; identified/quantified against reference standards. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weight measurement of residue. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies metal contaminants (e.g., Pb, Cd, Hg) by absorption of characteristic wavelength light by ground-state atoms in flame or graphite furnace. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Acid Value | Acid-Base Titration with NaOH | Measures acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color | Visual Comparison or Spectrophotometry (APHA/Pt-Co scale) | Evaluates color intensity by comparing sample against standardized platinum-cobalt solutions or measuring absorbance at 455 nm. |
| Density | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle with temperature-controlled measurement. |
| Refractive Index | Refractometry | Measures bending of light passing through liquid sample at specified temperature to assess purity and concentration. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and presence of impurities. |
| Organic Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects residual solvents by equilibrating sample in sealed vial, then analyzing vapor phase by GC-FID. |
