| Chemicals / Catalysis | Catalyst activity evaluation | Applied to qualitatively or quantitatively determine active site concentration in transition metal catalysts (e.g., zirconium- and titanium-based systems) via formation of colored complexes |
| R&D / Synthesis | Organic synthesis intermediate | Serves as a conjugated diene building block in Diels–Alder reactions or in the synthesis of organometallic compounds |
| Materials Science | Precursor for functional materials | Employed in the synthesis of metallocene derivatives or conjugated polymers exhibiting specialized optoelectronic properties |
Manufacturing Quality Control of DIPHENYLFULVENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison against a certified reference standard using UV detection at characteristic wavelength. |
| Related Substances | HPLC-UV | Separation and quantification of structurally similar impurities using gradient HPLC with UV detection and relative response factors. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents by gas chromatography with flame ionization detection using internal standard calibration. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration measuring water content via stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, based on atomic emission intensity at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Determination of inorganic residue after controlled combustion at 700-800 C followed by precise weighing of the ash. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement based on visual observation of solid-to-liquid phase change in a capillary tube under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against defined standards under controlled lighting and viewing conditions. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral components in solution at specified concentration and path length. |
| Organic Volatile Impurities (OVI) | GC-MS | Screening and semi-quantitative identification of non-specified volatile impurities using mass spectral library matching and selected ion monitoring. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution in dispersed powder sample based on angular dependence of laser light scattering intensity. |
