Industrial Applications of (S)-(-)-2-(1-HYDROXYETHYL)PYRIDINE
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Chiral auxiliary or chiral ligand for asymmetric synthesis of pharmaceutical intermediates, such as β-blockers (e.g., (S)-metoprolol) | Used as a chiral ligand in palladium- or iridium-catalyzed asymmetric allylic substitution and hydrogenation reactions |
| Agrochemicals | Chiral agrochemical intermediate for synthesizing optically active insecticides or fungicides | Applied as a chiral building block to construct heterocyclic agrochemical molecules containing stereocenters, such as stereoselective alkylation or acylation of pyridylethanol derivatives |
| Materials Science | Building block for chiral luminescent materials or liquid crystal molecules | Introduced into polymer backbones or side chains via esterification, etherification, or coupling reactions to modulate circularly polarized luminescence (CPL) performance |
Manufacturing Quality Control of (S)-(-)-2-(1-HYDROXYETHYL)PYRIDINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 210-230 nm, comparing peak area to a certified reference standard. |
| Enantiomeric Excess (ee) | Chiral HPLC | Separation on a chiral stationary phase followed by UV detection; ee calculated from peak area ratio of (S)- and (R)-enantiomers. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water in the sample. |
| Residual Solvents | GC-FID | Gas chromatographic separation with flame ionization detection, quantifying solvents against external calibration standards. |
| Heavy Metals | ICP-MS | Inductively coupled plasma mass spectrometry for trace-level quantification of elements such as Pb, Cd, Hg, and As. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 500-600 C followed by sulfuric acid treatment and final weighing of residual inorganic salts. |
| Optical Rotation | [alpha]D Measurement | Measurement of plane-polarized light rotation in solution using a digital polarimeter, reported at specified concentration and wavelength. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination using calibrated glass electrode in a saturated aqueous suspension or dilute solution. |
| Appearance | Visual Inspection | Assessment of color and clarity against water-white standard under controlled lighting and against white background. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using calibrated capillary apparatus per USP <741>. |
| Related Substances | HPLC-UV (Forced Degradation) | Stability-indicating method with acidic, basic, oxidative, thermal, and photolytic stress conditions to detect and quantify degradants. |
