| Fine Chemicals | Used as a precursor for fragrances and flavorings | Converted into odor-specific compounds via reactions such as hydrogenation and esterification |
| Electronic Chemicals | Production of photoactive components in photoresists | Incorporated into photoresist formulations following photosensitization treatment |
Manufacturing Quality Control of 4-Vinylphenol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Appearance | Visual Inspection | Assessment of physical state and color by observation against a white background under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary apparatus per USP <741>. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine-based reagent to quantify water based on stoichiometric reaction. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature ashing at 700-800 C. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion and plasma emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride anion using suppressed conductivity detection after aqueous extraction. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized NaOH solution using phenolphthalein indicator. |
| Peroxide Value | Iodometric Titration | Oxidation of potassium iodide by peroxides to liberate iodine, titrated with standardized sodium thiosulfate. |
| Residual Solvents | GC-FID | Separation and quantification of volatile organic solvents (e.g., toluene, ethyl acetate) using flame ionization detection. |
| Color (APHA) | UV-Vis Spectrophotometry | Measurement of yellowness index via absorbance at 430 nm in a 10 cm cell relative to platinum-cobalt standards. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using Mie scattering theory to determine volume-based size distribution. |
