Manufacturing Quality Control of 3,4,5-Trimethoxybenzoyl chloride
| 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. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acid 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 | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg, As) by plasma excitation and elemental emission spectroscopy. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects residual chloride ions via silver nitrate titration monitored by silver electrode potential change. |
| Color | Visual Comparison or Spectrophotometry (APHA/Pt-Co Scale) | Evaluates sample color intensity relative to platinum-cobalt standard solutions at 455 nm. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral impurities or degradation products. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Identifies and quantifies volatile organic solvents (e.g., dichloromethane, acetone) by equilibrium vapor phase analysis. |
| Related Substances | HPLC with UV Detection | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV absorbance at 254 nm. |
| pH of Aqueous Solution | pH Meter Measurement | Determines acidity/basicity of aqueous suspension or hydrolyzed sample using calibrated glass electrode. |
