| Industry | Application | Process |
|---|---|---|
| Coatings & Inks | Photoinitiator | Used in UV-curing reactions |
| Printing | UV-curable ink additive | Applied in free-radical polymerization |
| Cosmetics | UV absorber | Incorporated as a stabilizer in formulations |
| Polymers | Resin modifier | Blended to enhance thermal stability and mechanical properties |
| Electronic Chemicals | Photoresist component | Employed as a crosslinker in photochemical reactions |
| Pharmaceutical Intermediates | Synthetic raw material | Utilized in organic synthesis reactions |
| Detection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, and visible impurities under natural light or standard illumination. |
| Purity (Main Component Content) | High-Performance Liquid Chromatography (HPLC) | Utilize a reversed-phase C18 column with UV detection (typically at 254 nm or set according to maximum absorption wavelength). Quantitative analysis is performed by comparison with reference standards to assess main component content. |
| Gas Chromatography (GC) | Applicable to volatile samples. Separation is achieved using capillary columns and detection via FID; used for purity determination and residual solvent analysis. | |
| Structural Confirmation | Fourier Transform Infrared Spectroscopy (FTIR) | Determine characteristic functional group absorption peaks (e.g., carbonyl C=O around 1650 cm⁻¹, aromatic ring skeletal vibrations), compared with standard spectra to confirm molecular structure. |
| Nuclear Magnetic Resonance Spectroscopy (NMR) | ¹H-NMR and ¹³C-NMR are used for precise structural elucidation, confirming methyl groups, substitution positions on aromatic rings, and overall chemical environment. | |
| Melting Point | Melting Point Determination (Capillary Method) | Measure initial and final melting temperatures using a melting point apparatus. Compare results with literature values (typically around 55–60°C, depending on the specific compound) to assess purity. |
| Moisture Content | Karl Fischer Titration | Determine water content in samples using electrochemical titration principles. Available in volumetric or coulometric modes, suitable for trace moisture analysis. |
| Residual Solvents | Gas Chromatography (GC) | Based on ICH guidelines, use headspace injection-GC/FID to detect potentially residual organic solvents (e.g., methanol, ethanol, acetone, toluene). |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determine levels of heavy metals such as lead, cadmium, mercury, and arsenic to ensure compliance with pharmaceutical or industrial safety standards. |
| Ash/Charring Residue | Charring Residue Method | Incinerate the sample at high temperature until constant weight to measure total non-volatile inorganic impurities, reflecting the level of inorganic contaminants. |
| Individual Impurities and Total Impurities | HPLC Method | Analyze peak areas from HPLC chromatograms to calculate percentages of individual and total impurities, assessing the impurity profile. |
