Industrial Applications of 253265-97-3
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthesis of antiviral drug intermediates | Used in organic synthesis and chiral catalysis |
| Agrochemicals | Preparation of high-efficiency, low-toxicity pesticide intermediates | Applied in cyclization and acylation reactions |
| Fine Chemicals | Synthesis of chiral compounds | Employed in asymmetric synthesis and protecting group chemistry |
Manufacturing Quality Control of 253265-97-3
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and physical state (e.g., white solid, powder) under natural or standard lighting to determine if it meets specifications. |
| Identification (Structural Confirmation) | Nuclear Magnetic Resonance Spectroscopy (NMR) (¹H NMR, ¹³C NMR) |
Determine chemical shifts, coupling constants, and integration areas of hydrogen and carbon atoms in the compound. Compare with reference spectra to confirm molecular structure and stereochemistry. |
| Purity Analysis (Assay) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with isocratic or gradient elution and a UV detector (e.g., 210–254 nm). Determine main component purity using external standard or area normalization methods. |
| Chiral Purity (Enantiomeric Excess) | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Use chiral stationary phase columns (e.g., Chiralpak AD-H, OD-H) to separate enantiomers and determine the enantiomeric excess (ee) of the target enantiomer. |
| Water Content | Karl Fischer Titration | Quantitatively determine water content based on the reaction of iodine and sulfur dioxide with water in anhydrous methanol. Suitable for trace moisture analysis. |
| Residual Solvents | Gas Chromatography (GC) | In accordance with ICH Q3C guidelines, use capillary columns and FID detection to identify and quantify organic solvents potentially remaining from manufacturing (e.g., methanol, ethanol, ethyl acetate, dichloromethane). |
| Related Substances (Impurity Profiling) | HPLC-UV / LC-MS | Use HPLC to detect degradation products, by-products, or process-related impurities; combine with mass spectrometry (LC-MS) to identify structures of unknown impurities. |
| Melting Point | Melting Point Apparatus | Determine initial and final melting temperatures using automated or capillary melting point instruments, useful for identification and assessment of crystalline purity. |
| Polymorphic Form Analysis | X-Ray Powder Diffraction (XRPD) Differential Scanning Calorimetry (DSC) |
XRPD is used to identify crystal structure and polymorphic forms; DSC measures melting behavior, crystallinity, and thermal stability. |
| Particle Size Distribution | Laser Diffraction Analysis (LDI) | For solid active pharmaceutical intermediates, particle size distribution may be measured prior to formulation processing, as it affects solubility and downstream manufacturability. |
