Industrial Applications of CIS-BICYCLO[3.3.0]OCTANE-3,7-DIONE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Organic synthesis intermediate for constructing bridged-ring scaffold structures in candidate drug molecules | Used as a key chiral intermediate in multistep syntheses, such as reductive amination and olefin metathesis, to construct biologically active molecules containing a [3.3.0] bicyclic system |
| Fine Chemicals | Chiral ligand or precursor to catalyst supports for asymmetric catalysis research | Processed via selective monofacial reduction or derivatization to prepare C3/C7-functionalized chiral ligands for Pd- and Rh-catalyzed asymmetric cycloaddition reactions |
| Materials Science | Model compound for high-strain bridged-ring systems, used to study the relationship between ring strain and photo-/thermal-responsive properties | Subjected to controlled pyrolysis or photoexcitation to investigate ring-opening kinetics and radical generation behavior, supporting the design of novel energy storage materials |
Manufacturing Quality Control of CIS-BICYCLO[3.3.0]OCTANE-3,7-DIONE
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with gradient elution of water-acetonitrile or methanol, and UV detection (210–254 nm). The main component purity is calculated by peak area normalization, which effectively separates structural analogs and degradation products. |
| Content Determination | HPLC or Gas Chromatography (GC) | HPLC is suitable for thermally unstable components, while GC is used when the sample has good volatility (requires derivatization). External standard method or internal standard method is used for quantification to ensure the content meets pharmacopoeia or enterprise standards (e.g., ≥98.0%). |
| Solvent Residue | Gas Chromatography - Headspace Sampling (HS-GC) | Headspace sampling combined with FID detection is used to determine residual solvents such as ethanol, acetone, and ethyl acetate according to ICH Q3C guidelines, ensuring compliance with residual solvent limits. |
| Water Content | Karl Fischer Titration | Koulometric or volumetric methods are used to determine trace amounts of water in the sample, suitable for moisture-sensitive ketone compounds, ensuring water content is below 0.5% (adjusted based on use). |
| Melting Point Determination | Capillary Melting Point Apparatus | Determine the melting point range (typically around 85–95°C) for preliminary identification and purity assessment. A pure substance should have a narrow melting range (≤2°C). |
| UV-Vis Absorption Spectra | UV-Vis Spectrophotometry | Measure absorption characteristics in ethanol or methanol between 200–300 nm, confirming conjugated carbonyl structures (e.g., λmax ≈ 240–260 nm), assisting in structural confirmation and impurity screening. |
| Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (¹H NMR / ¹³C NMR) | Confirm molecular framework and cis configuration through proton and carbon spectra (e.g., coupling constant J≈8–10 Hz between H-3 and H-7, indicating cis-diketone vicinal protons). It is the gold standard for structural identification in quality control. |
| Specific Rotation (if chiral center exists) | Optical Rotatory Dispersion (ORD) Measurement | If the molecule contains a chiral center (e.g., asymmetric substitution), measure specific rotation [α]D²⁵ and compare it with the reference standard to confirm optical purity. This compound is an meso compound, theoretically non-optically active, and needs verification. |
| Impurity Profile Analysis | HPLC-MS / LC-MS/MS | Combined mass spectrometry detects unknown impurities, and molecular ion peaks and fragment ions are used to infer degradation products (e.g., dehydration, oxidation, ring-opening products), supporting method development and impurity control strategies. |
| Appearance and Color | Visual Inspection + Colorimetry | Observe solid form (white to off-white crystalline powder), and use a colorimeter or colorimetric method to determine yellow index (YI), ensuring no significant coloring impurities. |
