Manufacturing Quality Control of trans-4-Phenyl-3-buten-2-one
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies trans-benzylideneacetone by peak area comparison against a certified reference standard using a polar capillary column. |
| Appearance | Visual Inspection | Assesses physical state and presence of visible particulates, discoloration, or phase separation under controlled lighting. |
| Color (APHA) | Visual Comparison to APHA Color Standards | Compares sample color in solution to standardized platinum-cobalt scale solutions using a Nessler tube. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid using calibrated melting point apparatus. |
| Loss on Drying | Gravimetric Analysis (105 C, 2 h) | Determines volatile content by weight loss after drying under specified temperature and time conditions. |
| Residue on Ignition | Sulfated Ash Gravimetry | Measures non-volatile inorganic residue after controlled charring and ashing at 700-750 C. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemically quantifies water via iodine generation and stoichiometric reaction with sample moisture. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures total heavy metal content after acid digestion by absorption of characteristic atomic line radiation. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride ions by titration with silver nitrate and endpoint determination via silver electrode potential change. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies structurally similar impurities using reversed-phase C18 column and UV absorbance at 254 nm. |
| Acid Value | Acid-Base Titration with NaOH | Determines free carboxylic acid content by titration with standardized sodium hydroxide using phenolphthalein indicator. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral impurities or degradation products in solution. |
