Industrial Applications of 2,3-Dihydrobenzo[b]furan-5-carbaldehyde
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Used as a pharmaceutical intermediate in the synthesis of bioactive compounds, including antidepressants, anti-inflammatory agents, and anticancer candidates | Applied in organic synthesis reactions—including reduction, oxidation, condensation, and nucleophilic addition—to construct the core structure of target drug molecules |
| Agrochemicals | Used as an intermediate in the synthesis of novel pesticides or plant growth regulators | Employed in multistep syntheses to introduce the benzofuran scaffold, facilitating heterocycle construction or functional group transformation |
| Fine Chemicals | Used as a precursor in the preparation of fragrances, liquid crystal materials, or functional polymers | Applied as an aromatic aldehyde in Wittig reactions, Knoevenagel condensations, or Grignard reactions to produce fine chemicals with specific performance attributes |
Manufacturing Quality Control of 2,3-Dihydrobenzo[b]furan-5-carbaldehyde
| Test Item | Commonly Used Testing Methods | Method Summary |
|---|---|---|
| Identity | Infrared Spectroscopy (IR) Proton Nuclear Magnetic Resonance (¹H NMR) Mass Spectrometry (MS) |
Confirm functional groups through characteristic IR absorption peaks (e.g., aldehyde C=O ~1700 cm⁻¹, aromatic C=C, etc.); ¹H NMR identifies protons on the benzofuran ring and aldehyde proton (δ ≈ 9.8–10.0 ppm), along with coupling patterns; MS confirms molecular ion peak (m/z = 148 [M]⁺) and characteristic fragments. Together, these methods confirm compound structure. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column with methanol-water or acetonitrile-water as the mobile phase. Detection is performed using a UV detector (typically at ~254 nm or optimized based on maximum absorption). The assay is conducted using an external standard method or area normalization, suitable for quantitative analysis of 2,3-dihydrobenzofuran-5-carbaldehyde in active pharmaceutical ingredients or intermediates. |
| Related Substances / Impurity Testing | High-Performance Liquid Chromatography (HPLC) | Same or modified chromatographic conditions as the assay, often with gradient elution, to separate and detect possible process-related impurities (e.g., unreacted starting material, oxidation byproducts, dehydration products). Impurities are quantified by comparison with reference standards or using relative response factors to control individual and total impurity limits. |
| Residual Solvents | Gas Chromatography (GC) | According to ICH Q3C guidelines, residual organic solvents (e.g., toluene, ethanol, dichloromethane) from the synthesis process are detected using headspace or direct injection GC-FID, ensuring compliance with safety limit requirements. |
| Water Content | Karl Fischer Titration | Determines the water content in the sample using volumetric or coulometric methods. Suitable for aldehyde compounds sensitive to moisture, ensuring stability and compliance with quality standards (typically ≤0.5%). |
| Melting Point | Capillary Melting Point Method | Determines the melting temperature range of solid samples, used as a physical constant for identity confirmation and purity assessment (literature value ~50–55 °C, may vary slightly depending on crystal form). |
| Appearance and Physical Characteristics | Visual Inspection | Observe the sample's color (typically colorless to light yellow liquid or low melting point solid), clarity, and presence of foreign matter, serving as a preliminary quality assessment. |
