| Chemicals | Intermediate | Serves as an intermediate in organic synthesis for constructing more complex molecular structures. |
Manufacturing Quality Control of 152628-02-9
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Chemical Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (¹H-NMR, ¹³C-NMR) | Confirm the molecular skeleton and substituent positions by characteristic peaks in hydrogen and carbon spectra (e.g., aromatic proton chemical shifts in benzimidazole rings δ 7.5–8.5 ppm, methyl/ethylene signals in alkyl chains), comparing with standard spectra or literature data. |
| High-Resolution Mass Spectrometry (HRMS) | Use ESI or EI sources to obtain accurate molecular weight, verify molecular formula (e.g., C₂₀H₂₁N₄), confirm target compound's molecular ion peak [M+H]⁺ or [M]⁺, and exclude interference from isomers. | |
| Content Determination (Main Component Purity) | High-Performance Liquid Chromatography (HPLC) | Use a C18 reverse-phase column with acetonitrile-water (containing 0.1% formic acid or trifluoroacetic acid) as the mobile phase for gradient elution, using a UV detector (254–280 nm) for quantification; calculate main component content using external standard or area normalization methods. |
| Ultra-High-Performance Liquid Chromatography (UHPLC) | Use smaller particle size packing (<2 μm) to shorten analysis time and improve resolution and sensitivity; suitable for simultaneous detection of trace impurities and main components. | |
| Impurity Profile Analysis | HPLC / UHPLC-MS Coupled Techniques | Combined with mass spectrometer detector to identify degradation products, synthetic intermediates, or by-products (e.g., unclosed precursors, dealkylated products), infer impurity structures through fragment ions. |
| Residual Solvent Detection | Gas Chromatography (GC-FID/MS) | According to ICH Q3C standards, use headspace or direct injection to detect residual solvents such as acetone, ethanol, DMF, acetonitrile used in synthesis, quantify using internal standard method. |
| Moisture Content | Karl Fischer Titration | Determine trace moisture using coulometric or volumetric methods to ensure moisture content meets pharmaceutical or high-purity requirements (usually ≤0.5%). |
| Melting Point Determination | Melting Point Apparatus Method | Determine melting range (e.g., 210–215°C) to preliminarily judge crystal form consistency and purity, used as an auxiliary identification method. |
| UV-Visible Absorption Spectroscopy | UV-Vis Spectrophotometry | Determine maximum absorption wavelength (λmax, usually between 260–290 nm) in ethanol or methanol for rapid comparison and quantitative support; however, specificity is low, often used as an auxiliary confirmation method. |
| Polymorphic Analysis (if applicable) | X-ray Powder Diffraction (XRPD) | If the substance is polymorphic, confirm polymorphic consistency using XRPD spectra to avoid changes in solubility or stability due to polymorphic differences (applicable to pharmaceutical raw materials). |
| Heavy Metals and Inorganic Impurities | ICP-MS or ICP-OES | Detect heavy metal residues such as As, Pb, Cd, Hg, complying with pharmacopoeia (e.g., USP/EP) requirements for elemental impurities, especially for pharmaceutical-grade raw materials. |
| Chloride/Sulfate and Other Inorganic Ions | Ion Chromatography (IC) | Detect halogen ions or sulfate introduced during production to ensure inorganic impurities meet limit requirements (e.g., Cl⁻ ≤10 ppm). |
