Industrial Applications of 98760-08-8
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Chiral intermediate for synthesizing antiviral protease inhibitors (e.g., HIV protease inhibitors) | Produced via asymmetric synthesis or chiral resolution; employed in multi-step organic synthesis using carbamate protecting group strategies to construct active molecular scaffolds containing oxirane and phenethylamine motifs |
Manufacturing Quality Control of 98760-08-8
| Test Item | Commonly Used Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, physical state (e.g., white solid, powder, or oily substance), and whether visible foreign matter is present. |
| Identification | Infrared Spectroscopy (IR) | Confirm characteristic functional groups (e.g., epoxy, carbamate, benzene ring) by comparing the infrared absorption spectrum with reference spectra. |
| Nuclear Magnetic Resonance Spectroscopy (¹H-NMR, ¹³C-NMR) | Analyze chemical shifts, coupling constants, and integration areas in proton and carbon spectra to confirm the compound's structure and stereochemistry. | |
| Purity/Content Determination | High-Performance Liquid Chromatography (HPLC) | Quantify the main component using a reversed-phase C18 column and UV detector (typically 210–260 nm) based on retention time and peak area. |
| Impurity Analysis | HPLC or GC-MS | Detect related substances (e.g., starting materials, intermediates, degradation products), with optional mass spectrometry for impurity identification. |
| Water Content | Karl Fischer Titration | Accurately determine water content in the sample, suitable for moisture-sensitive carbamate compounds. |
| Residual Solvents | Gas Chromatography (GC) | Detect organic solvents potentially remaining from the manufacturing process (e.g., methanol, ethanol, ethyl acetate, dichloromethane) according to ICH guidelines. |
| Specific Optical Rotation | Polarimetry | Measure the specific optical rotation to verify optical purity and stereochemistry (due to multiple chiral centers). |
| Melting Point | Melting Point Apparatus | Determine the melting point range using the capillary method to assist in assessing compound purity and crystal form consistency. |
| Particle Size Distribution (if applicable) | Laser Particle Size Analysis | If the compound is a solid powder used in formulations, control the particle size distribution to ensure dissolution properties and bioavailability. |
| Thermal Stability | Differential Scanning Calorimetry (DSC) | Analyze melting behavior, polymorphic transitions, and thermal decomposition temperatures to evaluate thermal stability. |
