Industrial Applications of 23788-74-1
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Chiral synthetic intermediate for antibiotics, antiviral agents, and cardiovascular drugs | Used as a hydroxyl protecting group or chiral auxiliary in organic synthesis; employed in esterification, condensation, and related reactions |
| Agrochemicals | Intermediate for chiral agrochemicals, including precursors to insecticidal and fungicidal active ingredients | Introduces the dioxolane structure via nucleophilic substitution to construct specific chiral centers |
| Fine Chemicals | Synthesis of liquid crystal materials, fragrances, or specialty polymer monomers | Functions as a functionalization reagent to introduce protecting groups or modify functional groups within molecules |
Manufacturing Quality Control of 23788-74-1
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, state (e.g., white solid, powder, etc.) and whether it contains visible impurities. |
| Purity (Main Component Content) | High-Performance Liquid Chromatography (HPLC) | Use a reverse-phase C18 chromatographic column and a UV detector (typically at 254 nm or 220 nm) to determine the content of the target compound using an external standard method or area normalization method. |
| Chiral Purity (Enantiomeric Excess) | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Separate (R) and (S) enantiomers using a chiral stationary phase column (e.g., Chiralpak AD-H, AS-H), and calculate the enantiomeric excess (ee value). |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Analyze the hydrogen and carbon framework structure of the compound via ¹H NMR and ¹³C NMR to confirm the molecular structure and stereochemistry. |
| Structural Confirmation | Mass Spectrometry (MS) | Determine the molecular ion peak using ESI or EI mass spectrometry to confirm the molecular weight; high-resolution mass spectrometry (HRMS) can verify the molecular formula. |
| Residual Solvents | Gas Chromatography (GC) | According to ICH guidelines, detect residual organic solvents used in the production process (e.g., methanol, ethanol, ethyl acetate, etc.). |
| Water Content | Karl Fischer Titration | Determine the water content of the sample; suitable for ester compounds sensitive to moisture. |
| Melting Point | Melting Point Determination Method | Determine the melting range of the compound using capillary method or automatic melting point instrument to assist in judging purity and crystalline consistency. |
| Infrared Spectrum (IR) | Fourier Transform Infrared Spectroscopy (FT-IR) | Analyze characteristic functional group absorption peaks (e.g., ester carbonyl ~1740 cm⁻¹, aromatic C=C, S=O, etc.) to aid in structural confirmation. |
