| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Antimicrobial drug intermediate | Key cyclic intermediate for synthesizing third-generation quinolone antibiotics (e.g., gatifloxacin); used to construct the quinolone core via N-alkylation, fluorination, and related steps |
| Detection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Chemical Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Utilizes ¹H-NMR and ¹³C-NMR to analyze chemical shifts and coupling constants of hydrogen and carbon atoms, confirming molecular framework and substitution positions. |
| Fourier Transform Infrared Spectroscopy (FT-IR) | Detects characteristic functional group absorption peaks (e.g., nitrile -C≡N ~2200 cm⁻¹, hydroxyl -OH ~3200–3500 cm⁻¹) to assist in structural verification. | |
| Mass Spectrometry (MS) | Employs ESI or EI ionization sources to determine molecular ion peaks ([M+H]⁺ or M⁺•), confirming molecular weight and fragmentation patterns to support structural elucidation. | |
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | Uses C18 reversed-phase column with UV detector (e.g., 254 nm or set according to maximum absorbance wavelength) for quantitative determination of main component and detection of related impurities. |
| Ultra-Performance Liquid Chromatography (UPLC) | Enhances separation efficiency and speed, suitable for rapid purity assessment and trace impurity analysis. | |
| Content Determination | HPLC External Standard Method / Internal Standard Method | Quantifies target compound content by comparing peak areas with known concentration reference standards, ensuring batch-to-batch consistency. |
| Impurity Limit Testing | HPLC Gradient Elution Method | Optimizes mobile phase gradient programs to separate and quantify potential process impurities, degradation products, etc., meeting ICH Q3A/B requirements. |
| Residual Solvent Testing | Headspace Gas Chromatography (HS-GC) | Performs qualitative and quantitative analysis of organic solvents (e.g., methanol, acetonitrile, DMF) potentially remaining from synthesis, in accordance with ICH Q3C guidelines. |
| Drying Loss / Moisture Content | Karl Fischer Titration | Determines moisture content in samples to prevent adverse effects on stability or reactivity. |
| Drying Loss Method | Dries the sample at a specified temperature until constant weight, calculating total volatile substances (including water and other volatile components). | |
| Melting Point Determination | Capillary Melting Point Apparatus | Measures the melting temperature range as a physical constant for preliminary identification and purity assessment (pure compounds exhibit narrow melting ranges). |
| Polymorphism/Solid-State Characterization | X-Ray Powder Diffraction (XRPD) | Analyses crystal structure-specific diffraction peaks to confirm the presence or absence of polymorphic forms, ensuring consistency in formulation performance. |
| pH Value / Acidity/Alkalinity | pH Meter Measurement (in Solution State) | Prepares a solution of the sample at a defined concentration and measures its pH value to evaluate acid-base properties and their impact on formulations. |
| Heavy Metal Residue | ICP-MS or Atomic Absorption Spectroscopy (AAS) | Tests for elemental impurities such as lead, arsenic, cadmium, and mercury according to pharmacopoeial general rules, ensuring compliance with safety limits (e.g., ICH Q3D). |
