Industrial Applications of 85312-59-0
| Industry | Application | Process |
|---|---|---|
| Liquid Crystal Display (LCD) Materials | Component of liquid crystal mixtures to broaden the nematic phase temperature range, enhance dielectric anisotropy, and improve optical performance | Formulation synthesis: blended with other mesogenic compounds in precise ratios to produce liquid crystal mixtures exhibiting required electro-optical properties for use in TN, STN, or IPS displays |
Manufacturing Quality Control of 85312-59-0
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm based on peak area comparison against certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., isomers, dehalogenated by-products) using gradient HPLC and UV detection. |
| Residual Solvents | GC-FID | Determines trace organic solvents (e.g., toluene, heptane, IPA) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Measures water by volumetric or coulometric titration where iodine reacts stoichiometrically with water in pyridine/methanol medium. |
| Heavy Metals | ICP-OES | Quantifies metal impurities (e.g., Fe, Pb, Ni) after acid digestion by measuring atomic emission intensities at characteristic wavelengths. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube and controlled heating ramp. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or phase separation against white/black background under controlled lighting. |
| Bulk Density | ASTM D1895 | Measures mass per unit volume of freely settled powder using standardized cylinder and funnel apparatus. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of dry powder by measuring angular variation in intensity of scattered laser light. |
| Optical Rotation | Polarimetry | Determines specific rotation using sodium D-line light through a solution in specified solvent and path length to confirm chiral integrity. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic residue remaining after high-temperature ashing (600-750 C) followed by precise weighing. |
