Industrial Applications of 1737-93-5
| Industry | Application | Process |
|---|---|---|
| Pesticides | Key intermediate for synthesizing novel fluorinated insecticides (e.g., flupyradifurone) | Constructs C–N bonds via nucleophilic substitution or coupling reactions to introduce amine side chains |
| Pharmaceuticals | Structural building block for fluorinated pyridine-based antibacterial and antitumor agents | Introduces aryl or heteroaryl substituents via metal-catalyzed cross-coupling (e.g., Suzuki, Heck reactions) |
| Materials Science | Monomer for high-performance fluorinated polymers used in corrosion-resistant coatings and electronic encapsulation materials | Undergoes condensation polymerization with diamines or diols to form fluorinated polyimide or polyetherketone backbones |
Manufacturing Quality Control of 1737-93-5
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against certified reference standard under optimized chromatographic conditions. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of structurally related impurities using reversed-phase C18 column and gradient elution. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) with FID | Volatile organic solvents are vaporized in sealed vials and analyzed by GC after equilibrium partitioning into headspace. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water in the sample. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anionic impurities on ion-exchange column followed by quantitative detection via electrical conductivity. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element quantification of metallic impurities based on element-specific atomic emission lines after acid digestion. |
| Acid-Base Impurities | Acid-Base Potentiometric Titration | Titration with standardized NaOH or HCl to determine total acidic or basic impurities by pH inflection point detection. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range over which solid transforms to liquid, compared to reference standard. |
| Appearance | Visual Inspection in Clear Glass Container | Assessment of physical state, color, and presence of particulates or phase separation under controlled lighting. |
| Residue on Ignition | Gravimetric Analysis after High-Temperature Ashing | Mass of non-volatile inorganic residue determined after incineration at 700-800 C in platinum crucible. |
| Particle Size Distribution | Laser Diffraction Particle Size Analyzer | Measurement of scattered laser light intensity as function of angle to derive volume-based particle size distribution. |
| Specific Optical Rotation | Polarimetry | Quantification of chiral impurity or enantiomeric excess based on rotation of plane-polarized light in solution. |
