Industrial Applications of 149022-15-1
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Intermediate for synthesizing antitumor agents (e.g., benzothiazole-based kinase inhibitors) | Palladium-catalyzed cross-coupling with haloarenes in inert solvent, followed by deprotection and salt formation |
| Agrochemicals | Intermediate for fungicidal compounds (benzothiazole-based) | Cyclization with thiophosgene or carbon disulfide, followed by oxidation, alkylation, and other steps to construct the active molecular scaffold |
| Materials Science | Dopant-assisting agent in the electron-transport layer of organic light-emitting diode (OLED) devices | Coevaporation with host material (e.g., TPBi) prior to vacuum deposition to tune energy-level alignment and charge-carrier balance |
Manufacturing Quality Control of 149022-15-1
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of impurities using gradient HPLC-UV; identification and quantification against reference standards or threshold limits. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine-based reagent to determine total water content based on stoichiometric reaction. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 700-800 C to constant weight and measuring inorganic residue as percentage of original mass. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and others after acid digestion, using plasma emission spectroscopy. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using silver indicator electrode; endpoint detected by potential change. |
| pH of Aqueous Solution | pH Meter Measurement | Direct measurement of pH in a 1% w/v aqueous suspension using calibrated pH electrode. |
| Organic Volatile Impurities | GC-FID | Headspace or direct injection GC with flame ionization detection to quantify residual solvents per ICH Q3C guidelines. |
| Particle Size Distribution | Laser Diffraction | Analysis of dispersed sample in liquid medium using light scattering to determine D10, D50, D90 values. |
| Bulk Density | USP <616> Tap Density Method | Measurement of mass per unit volume before and after mechanical tapping to determine bulk and tapped density. |
| Microbial Limits | Membrane Filtration | Filtration of aqueous extract followed by incubation on soybean-casein digest agar and sabouraud dextrose agar for total aerobic count and yeast/mold. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution at specified concentration and wavelength (e.g., 589 nm). |
