Manufacturing Quality Control of 3-OXO-3-O-TOLYL-PROPIONIC ACID ETHYL ESTER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | GC-FID | Quantifies main component using gas chromatography with flame ionization detection based on peak area response relative to calibrated standard. |
| Related Substances | HPLC-UV | Separates and quantifies impurities using reversed-phase high-performance liquid chromatography with ultraviolet detection at specified wavelength. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration where iodine reacts stoichiometrically with water in a methanol-based electrolyte. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing and subsequent weighing. |
| Heavy Metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg, As) via inductively coupled plasma optical emission spectrometry using element-specific emission lines. |
| Chloride Content | Potentiometric Titration | Determines chloride ions using silver nitrate titrant with silver-sulfide electrode detecting endpoint potential change. |
| Acid Value | Acid-Base Titration | Measures free carboxylic acid content by titration with standardized potassium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowish tint by comparing sample color to APHA platinum-cobalt standard solutions or measuring absorbance at 430 nm. |
| Density | Oscillating U-tube Densitometry | Determines mass per unit volume from resonant frequency shift of a vibrating U-shaped glass tube filled with sample. |
| Refractive Index | Refractometry | Measures ratio of light velocity in air versus sample at specified temperature using critical angle principle. |
| Boiling Point Range | Capillary Boiling Point Apparatus | Determines temperature interval over which sample distills under reduced pressure using calibrated capillary method. |
| Organic Volatile Impurities | GC-FID with Headspace | Identifies and quantifies residual solvents (e.g., ethanol, toluene) using headspace gas chromatography with flame ionization detection. |
