Industrial Applications of 1171891-31-8
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Boronic ester reagent for Suzuki-Miyaura cross-coupling reactions to synthesize pyridine-containing drug candidates (e.g., kinase inhibitors, antitumor compounds) | Under palladium catalysis (e.g., Pd(dppf)Cl₂, Pd(PPh₃)₄), undergoes cross-coupling with aryl/heteroaryl halides or pseudohalides to construct C–C bonds; typically conducted under basic conditions (e.g., K₂CO₃, Cs₂CO₃) in inert solvents (e.g., 1,4-dioxane, DMF) |
| Materials Science | Building block for conjugated organic semiconductor molecules and ligands in metal–organic frameworks (MOFs), enhancing charge-carrier mobility and photoresponse performance | Functions as a functionalized synthon in multistep coupling and coordination assembly; commonly employed in Suzuki coupling with comonomers such as bromothiophene or iodocarbazole to prepare π-conjugated polymers |
| Agrochemical R&D | Key intermediate for synthesizing novel pyridine-containing boronic acid-based targeted insecticides and plant growth regulators | After incorporation into heterocyclic scaffolds via Suzuki coupling, subjected to further amidation or sulfonylation to optimize biological activity and metabolic stability |
Manufacturing Quality Control of 1171891-31-8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., residual starting materials, hydrolysis products) via gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, methanol, toluene) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration based on iodine generation and stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pd, Ni, Fe) using inductively coupled plasma mass spectrometry for ultra-trace sensitivity. |
| Residual Palladium | ICP-OES | Measures palladium catalyst residue via inductively coupled plasma optical emission spectrometry after acid digestion. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or discoloration against established reference standards. |
| Loss on Drying | Gravimetric Analysis | Measures volatile loss by weight difference before and after controlled heating under specified time/temperature/vacuum conditions. |
| Specific Optical Rotation | Polarimetry | Determines chiral purity by measuring rotation of plane-polarized light in solution using sodium D-line. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or dispersed particle size distribution based on angular scattering pattern of laser beam. |
