Industrial Applications of 87414-44-6
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthesis of antiviral drug intermediates | Used as a key building block in multistep syntheses of cyclic amine- or lactone-based drugs |
| Pesticides | Synthesis of insecticide and fungicide intermediates | Applied to construct γ-lactone-containing active molecules, with the pesticide backbone formed via acylation or alkylation |
| Electronic Chemicals | High-purity solvent for semiconductor cleaning | Employed as a low-toxicity, high-boiling, high-solubility solvent in photoresist stripping and wafer cleaning processes |
| Polymers | Monomer for polyester and polyurethane modification | Utilized in ring-opening polymerization or transesterification to produce biodegradable polyester copolymers |
| Fine Fragrances & Flavors | Precursor for natural flavor compound synthesis | Converted via reduction or esterification into γ-lactone derivatives imparting creamy and nutty aroma notes |
Manufacturing Quality Control of 87414-44-6
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies gamma-butyrolactone II content by retention time and peak area comparison against a certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine-based reagent reacting stoichiometrically with water. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Evaluates yellowness by matching sample color to APHA platinum-cobalt standards or measuring absorbance at 455 nm. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Refractometry | Determines refractive index by measuring angle of light refraction at air-sample interface using calibrated prism. |
| Residue on Evaporation | Gravimetric Analysis | Quantifies non-volatile residue after controlled evaporation of a defined sample mass under specified temperature and vacuum. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures total heavy metals after wet digestion by atomic absorption of ground-state metal atoms in flame or graphite furnace. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Aldehyde Impurities | Derivatization GC-FID or HPLC-UV | Detects low-level aldehydes (e.g., acetaldehyde) via hydrazone derivatization followed by chromatographic separation and detection. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Quantifies volatile organic solvents by equilibrium partitioning into headspace gas followed by GC-FID analysis. |
| Non-Volatile Residue (NVR) | Gravimetric Analysis | Measures insoluble particulates and non-volatiles after filtration and drying of a filtered sample solution. |
