Manufacturing Quality Control of 3-OXO-3-M-TOLYL-PROPIONIC ACID ETHYL ESTER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main compound using reverse-phase HPLC with UV detection at characteristic wavelength, based on peak area comparison against reference standard. |
| Related Substances | HPLC-DAD | Identifies and quantifies impurities by retention time and UV spectral matching, using gradient elution and diode-array detection. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents (e.g., ethanol, ethyl acetate) via gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration using iodine generation in pyridine/methanol-based reagent. |
| Acid Value | Acid-Base Titration | Measures free carboxylic acid groups via titration with standardized NaOH solution using phenolphthalein indicator. |
| Color | Visual Comparison (APHA/Pt-Co Scale) | Evaluates color intensity by comparing sample solution in dilute solvent to platinum-cobalt standard solutions. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral centers in solution using sodium D-line light source. |
| Heavy Metals | ICP-OES | Quantifies metal impurities (e.g., Pb, Cd, Ni) after acid digestion by plasma excitation and elemental emission spectroscopy. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weighing of residual non-volatile matter. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Density | Digital Density Meter | Measures mass per unit volume at specified temperature using oscillating U-tube principle. |
