Industrial Applications of 4506-71-2
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Intermediate for synthesizing antihypertensive agents (e.g., thiazide diuretic analogues) and angiotensin II receptor antagonist derivatives | Undergoes N-alkylation with alkyl halides under basic conditions, or acyl chloride formation followed by condensation to construct heterocyclic side chains |
| Agrochemicals | Structural building block for novel insecticidal and fungicidal active ingredients containing a benzothiophene scaffold | Serves as a key coupling partner in Suzuki cross-coupling or Pd-catalyzed C–H activation reactions to introduce aryl or heteroaryl substituents |
| Materials Science | Precursor to organic semiconductor functional materials, used to prepare conjugated benzothiophene derivatives with charge-transport properties | Enables π-system expansion via Pd-catalyzed cross-coupling (e.g., Stille, Heck reactions), followed by thin-film fabrication for OTFT devices |
Manufacturing Quality Control of 4506-71-2
| 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 reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification by retention time matching with reference standards or threshold-based reporting. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents (e.g., ethanol, toluene) by gas chromatography with flame ionization detection using internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generated electrochemically or added reagent, based on stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, As, Hg) after acid digestion using inductively coupled plasma mass spectrometry with isotope dilution or external calibration. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions in aqueous extract using suppressed conductivity detection with anion-exchange column and sodium carbonate eluent. |
| Sulfate Content | Ion Chromatography | Measures sulfate ions in sample solution via anion-exchange chromatography with conductivity detection and external standard calibration. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by ignition at 700-800 C followed by precise weighing of residual non-volatile material. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating purity and identity via thermal behavior in a controlled capillary system. |
| Specific Optical Rotation | Polarimetry | Determines chiral purity and identity by measuring rotation of plane-polarized light in solution at specified concentration, temperature, and wavelength (e.g., 589 nm). |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of bulk sample against defined reference standards under controlled lighting and viewing conditions. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a standardized suspension (e.g., 1% w/v in water) using calibrated glass electrode pH meter. |
