Industrial Applications of 134071-44-6
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Antifungal drug intermediate | Used in the synthesis of antifungal drugs such as ketoconazole and itraconazole |
| Agrochemicals | Agricultural fungicide intermediate | Applied in the synthesis of fungicidally active agrochemical compounds |
| Chemicals | Organic synthesis intermediate | Employed in constructing functional molecules containing an imidazole ring |
Manufacturing Quality Control of 134071-44-6
| Test Item | Commonly Used Testing Methods | Method Overview |
|---|---|---|
| Identity | High-Performance Liquid Chromatography (HPLC), Infrared Spectroscopy (IR), Nuclear Magnetic Resonance Spectroscopy (NMR) | Compare retention time of the sample with that of the reference standard by HPLC; match characteristic functional group absorption peaks in IR with standard spectra; use ¹H-NMR and ¹³C-NMR to confirm hydrogen/carbon chemical shifts and coupling patterns in molecular structure for compound identification. |
| Purity and Related Substances | High-Performance Liquid Chromatography with UV/DAD Detection (HPLC-UV/DAD) | Use reversed-phase C18 column with gradient or isocratic elution; separate main and impurity peaks and detect using UV detector; calculate impurity content using external standard or self-comparison method to control total and individual impurity limits. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Quantitatively determine the content of the active ingredient using a validated HPLC method, typically by external or internal standard method; content is generally required to be between 98.0% and 102.0% (on anhydrous basis). |
| Loss on Drying / Karl Fischer Water | Karl Fischer Titration | Determine total bound and free water using volumetric or coulometric methods; control moisture content usually below 1.0% to prevent degradation or affect stability. |
| Residual Solvents | Gas Chromatography (GC) | According to ICH Q3C guidelines, detect residual organic solvents (e.g., methanol, ethanol, acetone, dichloromethane, toluene) used during manufacturing via headspace GC to ensure compliance with safety limits. |
| Polymorphism | X-ray Powder Diffraction (XRPD), Differential Scanning Calorimetry (DSC) | XRPD identifies characteristic peaks of different crystalline forms; DSC measures melting endothermic peak temperature and enthalpy change to assess crystallinity and polymorphic consistency, ensuring physical property stability between batches. |
| Particle Size Distribution | Laser Diffraction Analysis (LDI) | Measure D10, D50, D90 parameters after wet or dry dispersion; control particle size range to ensure dissolution and formulation uniformity (especially for solid dosage form raw materials). |
| Heavy Metals and Elemental Impurities | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectroscopy (AAS) | Test for metal impurities such as lead, cadmium, mercury, arsenic, and copper according to ICH Q3D; ensure compliance with Permitted Daily Exposure (PDE) standards. |
| Melting Point | Capillary Melting Point Method | Determine the temperature range at which the compound transitions from solid to liquid; used as a physical characteristic reference for identification and purity assessment; narrow melting range is generally required. |
| Specific Optical Rotation | Polarimetry | Prepare solution in specified solvent (e.g., methanol or ethanol); measure optical rotation using a sodium lamp light source and calculate specific optical rotation to control chirality and ensure consistency in compound configuration. |
