Manufacturing Quality Control of (S)-(-)-1-(P-TOLYL)ETHYLAMINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard under validated chromatographic conditions. |
| Enantiomeric Excess (ee) | Chiral Gas Chromatography (cGC) or Chiral HPLC | Separation of (S)- and (R)-enantiomers on a chiral stationary phase; ee calculated from relative peak areas. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration quantifying water via iodine generation and stoichiometric reaction with water in anhydrous medium. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile organic solvents quantified by equilibrium partitioning into headspace followed by GC-FID analysis. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Element-specific detection after acid digestion and nebulization; provides ultra-trace multi-element quantification. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Anion separation on ion-exchange column; chloride quantified by conductivity response relative to calibration standards. |
| Appearance and Color | Visual Inspection and APHA Color Scale | Comparison of sample solution (in specified solvent, e.g., methanol) against standardized platinum-cobalt color standards. |
| Specific Optical Rotation | [α]D | Measurement of plane-polarized light rotation at 589 nm (Na-D line) using a calibrated polarimeter; confirms chiral integrity and concentration. |
| Acid-Base Impurities (e.g., free amine, residual acid) | Non-aqueous Acid-Base Titration (with perchloric acid in glacial acetic acid) | Potentiometric or visual endpoint titration to quantify total basic nitrogen content relative to primary amine functionality. |
| Residual Catalyst (e.g., Pd, Rh) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantification of metal residues after microwave-assisted acid digestion via element-specific atomic emission intensities. |
| Related Substances | Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) with UV detection | Separation and quantification of structurally related impurities (e.g., ketone precursor, N-oxides, dimers) using gradient elution and UV absorbance at 210–254 nm. |
| pH (of aqueous solution) | pH Meter Measurement | Electrochemical measurement of hydrogen ion activity in a defined aqueous solution (e.g., 10% w/v in water) using calibrated pH electrode. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Determination of mass per unit volume at specified temperature (e.g., 20 °C) via resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Digital Refractometer | Measurement of light bending angle at air-sample interface at specified wavelength (e.g., 589 nm) and temperature (e.g., 20 °C). |
