Industrial Applications of 119018-29-0
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | As a sulfonylurea compound, used in research on antidiabetic activity or as a lead compound for insulin secretagogues | Prepared via organic synthesis for in vitro or in vivo pharmacological screening during drug discovery |
| Research | Used as a chemical probe or intermediate to investigate structure–activity relationships (SAR) of sulfonamide compounds | Synthesized through multistep organic synthesis (e.g., amide coupling, sulfonylation) for SAR studies |
Manufacturing Quality Control of 119018-29-0
| Test Item | Commonly Used Testing Methods | Method Overview |
|---|---|---|
| Identity | Infrared Spectroscopy (IR) | Confirm the presence of characteristic functional groups (e.g., sulfonamide, amide, carbonyl) by comparing the sample's IR absorption spectrum with that of a reference standard or spectral database. |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Analyze chemical shifts, integration areas, and coupling constants of hydrogen atoms in the molecule to verify structural consistency. | |
| Mass Spectrometry (MS or HRMS) | Determine molecular ion peaks and fragment ions to confirm molecular weight and elemental composition; high-resolution mass spectrometry provides accurate molecular formula information. | |
| Assay | High-Performance Liquid Chromatography with UV Detection (HPLC-UV) | Quantify the main component using a reversed-phase column and UV detector (typically 210–260 nm), with results calculated by external standard or area normalization method. |
| Ultra-Performance Liquid Chromatography (UPLC) | An upgraded HPLC technology with higher separation efficiency and shorter analysis time, suitable for high-throughput quality control. | |
| Related Substances / Impurities | HPLC-UV (Gradient Elution) | Use gradient elution to separate the main peak from process impurities and degradation products, with quantification by area normalization or using correction factors. |
| Liquid Chromatography-Mass Spectrometry (LC-MS) | Predict the structure of unknown impurities by combining retention time and mass spectral fragmentation information to identify the source of impurities. | |
| Residual Solvents | Headspace Gas Chromatography with Flame Ionization Detection (HS-GC-FID) | Measure residual organic solvents (e.g., methanol, acetonitrile, dichloromethane) from the synthesis process using headspace sampling and FID detection. |
| Water Content | Karl Fischer Titration | A highly specific and accurate method for water determination, suitable for active pharmaceutical ingredients sensitive to moisture. |
| Melting Point | Melting Point Apparatus | Measure the melting temperature range as a physical constant for preliminary identification and purity assessment (higher purity results in a narrower melting range). |
| Optical Rotation | Polarimetry (if applicable) | If the molecule contains a chiral center, specific optical rotation is measured to confirm stereochemical consistency. |
| pH (if in solution form) | pH Meter | Prepare a solution at a specified concentration and measure pH to assess acidity/basicity and stability. |
| Loss on Drying | Oven Weighing Method | Dry the sample at a specified temperature (e.g., 105°C) to constant weight and measure total weight loss due to volatiles, including moisture. |
| Sulfated Ash | High-Temperature Ashing | Determine the amount of inorganic impurities remaining after high-temperature incineration, used to evaluate residual inorganic salts or metal catalysts. |
