Industrial Applications of 185207-90-3
| Industry | Application | Process |
|---|---|---|
| Liquid Crystal Display (LCD) Materials | Component of liquid crystal mixtures to enhance dielectric anisotropy, birefringence, and response speed of the liquid crystal phase | Blended with other liquid crystal compounds in specific ratios following liquid crystal monomer synthesis to formulate liquid crystal media for TFT-LCD or STN-LCD applications |
Manufacturing Quality Control of 185207-90-3
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Chiral Purity | Chiral HPLC | Separation of enantiomers on a chiral stationary phase; quantification based on relative peak areas of (4S)-isomer vs. other stereoisomers. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., hexane, toluene, IPA) against calibration standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element detection and quantification of toxic metals (e.g., Pb, Cd, Hg, Ni) after acid digestion and matrix-matched calibration. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride anion using suppressed conductivity detection with carbonate/bicarbonate eluent. |
| Related Substances | HPLC-DAD | Detection and quantification of structurally related impurities (degradants, isomers, synthesis intermediates) using diode-array detection across 200–400 nm. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash content after high-temperature incineration (700–800 C) and weighing of residual residue. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid-to-liquid phase transition occurs, using calibrated digital apparatus per USP <741>. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample to obtain volume-based particle size distribution via Mie scattering theory. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral compound in solution at specified concentration and wavelength (e.g., 589 nm). |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determination of pH in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode and pH meter. |
