| Fragrances | Fragrance ingredient | Blended with other fragrance ingredients to enhance aromatic complexity |
Manufacturing Quality Control of 4-Hydroxyphenethyl alcohol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 275 nm, based on peak area comparison against reference standard. |
| Appearance | Visual Inspection | Assesses physical state and color by observing sample in clear glass container under controlled white light. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per USP <741>. |
| Loss on Drying | Gravimetric (105 C, 2 h) | Measures volatile content by weight loss after drying under specified temperature and time conditions. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Quantifies inorganic impurities by ignition of residue after sulfuric acid treatment and high-temperature ashing. |
| Heavy Metals | Colorimetric (Thioacetamide Method) | Detects Pb, Cd, Hg, As as colored sulfide complexes formed under controlled pH and compared to lead standard. |
| Chloride | Argentometric Titration (Mohr Method) | Determines chloride ion concentration via precipitation titration with silver nitrate using potassium chromate indicator. |
| Sulfate | Barium Sulfate Gravimetry | Quantifies sulfate as insoluble BaSO4 precipitate formed after barium chloride addition and dried weighing. |
| Related Substances | HPLC-DAD | Identifies and quantifies structurally related impurities using HPLC with diode-array detection and relative response factors. |
| Water Content | Karl Fischer Titration | Measures trace water via coulometric or volumetric titration based on iodine consumption in pyridine-methanol solvent system. |
| pH of Solution (1% w/v) | Potentiometric (pH Meter) | Determines acidity/basicity of aqueous solution using calibrated pH electrode per USP <791>. |
| Specific Optical Rotation | Polarimetry | Measures chiral purity by determining rotation angle of plane-polarized light through a standardized solution path length and concentration. |
