Manufacturing Quality Control of 4-Nitro-2,3-lutidine-N-oxide
| Test Item | Commonly Used Testing Method | Method Overview |
|---|---|---|
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase column with methanol/water or acetonitrile/buffer salt as the mobile phase. A UV detector (e.g., 254 nm or 280 nm) quantifies the purity of the main component and assesses impurity levels. |
| Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Analyzes chemical shifts and coupling constants of hydrogen and carbon atoms from ¹H NMR and ¹³C NMR spectra to confirm molecular structure and substitution positions. |
| Molecular Weight Determination | Mass Spectrometry (MS), such as ESI-MS or HRMS | Determines the quasi-molecular ion peak ([M+H]⁺ or [M-H]⁻) using electrospray ionization or high-resolution mass spectrometry to verify the molecular formula and theoretical molecular weight. |
| Impurity Identification and Quantification | HPLC-MS Coupling Technique | After HPLC separation, the sample is connected to a mass spectrometer for structural inference and quantification of unknown impurities, suitable for trace impurity analysis. |
| Residual Solvent Testing | Gas Chromatography (GC), headspace sampling | Uses capillary columns and FID or MS detectors to qualitatively and quantitatively analyze residual organic solvents (e.g., methanol, ethyl acetate) potentially present from the synthesis process. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying Method | Determines the weight loss of the sample after heating at a specified temperature (e.g., 105°C) to assess moisture or volatile content. |
| Melting Point Determination | Capillary Melting Point Apparatus or DSC | Measures the phase transition temperature range from solid to liquid, serving as a physical constant for identification and preliminary purity assessment. |
| Elemental Analysis | CHNS Elemental Analyzer | Measures the content of carbon, hydrogen, nitrogen, and sulfur elements in the sample and compares them with theoretical values to verify compositional consistency. |
| Crystal Form / Morphology Analysis | X-Ray Powder Diffraction (XRPD) | Uses characteristic diffraction peaks in the X-ray diffraction pattern to determine the crystalline form, ensuring batch-to-batch consistency, which affects solubility and stability. |
| UV Absorption Characteristics | UV-Visible Spectrophotometry (UV-Vis) | Scans the wavelength range of 200–400 nm to determine the maximum absorption wavelength (λmax) and molar absorptivity, used for identification or auxiliary quantification. |
