| Chemical Research | Laboratory reagent | Multi-step organic synthesis involving oxidation and substitution reactions |
Manufacturing Quality Control of 161798-01-2
| Detection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification (Identity) | Infrared Spectroscopy (IR) | Confirms molecular structure by characteristic functional group absorption peaks (e.g., aldehyde C=O, phenolic OH, ester C=O, thiazole ring). |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Analyzes chemical shifts, integration areas, and coupling constants of various protons; compares with reference spectra to confirm structure. | |
| Mass Spectrometry (MS, e.g., ESI-MS or EI-MS) | Determines molecular ion peak ([M+H]⁺ or M⁺•) and major fragment ions to verify molecular weight and structural fragments. | |
| Assay (Content Determination) | High-Performance Liquid Chromatography with UV Detection (HPLC-UV) | Uses reversed-phase C18 column with UV detection (typically at 254–280 nm) to quantitatively determine the main component content using external standard method. |
| Gas Chromatography (GC, if applicable) | If the compound has good thermal stability and volatility, GC-FID may be used for content analysis (less common for highly polar molecules). | |
| Related Substances (Impurities) | High-Performance Liquid Chromatography with Diode Array Detector/Ultraviolet Detection (HPLC-DAD/UV) | Uses gradient elution to separate the main peak from potential impurities (e.g., starting materials, intermediates, degradation products); quantifies using area normalization or correction factor methods. |
| Residual Solvents | Gas Chromatography (GC-FID or GC-MS) | Uses headspace or direct injection to detect organic solvents potentially residual from synthesis (e.g., ethanol, dichloromethane, DMF). |
| Water Content | Karl Fischer Titration | Accurately measures water content using either volumetric or coulometric Karl Fischer method, suitable for moisture-sensitive active pharmaceutical ingredients. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Oven Drying Method | Heated at a specified temperature (e.g., 105°C) until constant weight to determine total loss of volatile substances (including water and low-boiling solvents). |
| Melting Point | Melting Point Apparatus | Determined using capillary tube method or digital melting point instrument; provides physical constant for auxiliary identification and purity assessment. |
| Elemental Analysis (C, H, N, S) | Elemental Analyzer | Determines percentage content of carbon, hydrogen, nitrogen, and sulfur; compared with theoretical values to confirm chemical composition consistency. |
| Optical Rotation (if chiral molecule) | Polarimeter | If the molecule contains chiral centers, specific rotation must be measured to control optical purity (optional for this compound, which typically lacks chiral centers). |
