Industrial Applications of (S)-(-)-1-PHENYLETHANOL
| Industry | Application | Process |
|---|---|---|
| Fine Fragrances & Flavors | Floral fragrance ingredient used in formulating natural floral fragrances such as rose and jasmine | S-(-)-enantiomer obtained via chiral resolution or asymmetric synthesis; purified and directly incorporated into fragrance formulations |
| Pharmaceuticals | Chiral intermediate for synthesizing β-blockers (e.g., propranolol hydrochloride) and antidepressants | High-optical-purity S-(-)-phenylethanol produced via enzymatic kinetic resolution or asymmetric reduction of acetophenone, followed by esterification, substitution, and other reactions to construct the drug scaffold |
| Agrochemicals | Chiral intermediate for synthesizing chiral fungicides or plant growth regulators | Chiral alcohol component used in esterification reactions to generate biologically active chiral molecular structures |
| Chemical Reagents | Chiral reference standard or chiral auxiliary for analytical chemistry and asymmetric synthesis research | High-purity material obtained via chromatographic purification; used for chiral HPLC column calibration or as a chiral source in stereoselective reactions |
Manufacturing Quality Control of (S)-(-)-1-PHENYLETHANOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies S-(-)-phenylethanol by retention time and peak area against a certified reference standard. |
| Enantiomeric Purity | Chiral Gas Chromatography (cGC) or Chiral HPLC | Resolves R- and S-enantiomers using a chiral stationary phase; enantiomeric excess calculated from peak area ratio. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine-based reagent; stoichiometric reaction with water. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weighing of residual residue. |
| Heavy Metals | ICP-OES | Quantifies Pb, Cd, Hg, As, and other regulated metals by atomic emission after acid digestion. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions based on ion exchange and conductivity detection. |
| Acidity (as Acetic Acid) | Acid-Base Titration | Neutralizes acidic impurities with standardized NaOH solution using phenolphthalein indicator. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light at 20 °C using sodium D-line; confirms chiral integrity and concentration. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against water-white standard under controlled lighting. |
| Boiling Point | Distillation (Micro or Capillary) | Determines boiling range at specified pressure (e.g., 760 mmHg) using calibrated apparatus. |
| Refractive Index | Refractometry | Measures bending of light through liquid sample at 20 °C to assess purity and consistency. |
| Volatile Impurities | Headspace GC-MS | Identifies and quantifies low-boiling organic impurities (e.g., benzaldehyde, styrene) via headspace sampling and mass spectral detection. |
