Industrial Applications of Pentanoic acid, 4-oxo-, propyl ester
| Industry | Application | Process |
|---|---|---|
| Fragrances & Flavors | Used as a fruity fragrance agent, imparting pineapple, strawberry, and other fruit aromas | Incorporated directly into fragrance formulations or diluted for perfuming personal care and household products |
| Food Industry | Used as a food flavoring (FEMA No. 3451), providing sweet, fruity flavor notes | Added to end-use food products—including soft drinks, confectionery, and baked goods—within the maximum limits specified in GB 2760-2024 |
| Solvents & Auxiliaries | Used as an environmentally compatible medium-to-high boiling-point solvent, replacing conventional VOC solvents | Employed in coating, ink, and adhesive systems to control evaporation rate and film-forming properties |
| Organic Synthesis | Serves as a levulinic acid derivative and intermediate in transesterification, hydrogenation, and related reactions | Subjected to selective catalytic conversion—e.g., over acidic ion-exchange resins or metal catalysts—to produce γ-valerolactone or 1,4-pentanediol |
Manufacturing Quality Control of Pentanoic acid, 4-oxo-, propyl ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantitative separation and detection based on retention time and peak area against a certified reference standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Comparison of sample color intensity to APHA platinum-cobalt standard solutions at 455 nm. |
| Density at 20 degC | Digital Density Meter | Measurement of mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 degC | Refractometry | Determination of light bending angle at air-sample interface using calibrated Abbe refractometer. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of known sample mass to dryness followed by weighing of non-volatile residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal ions after acid digestion and chelation, based on absorption of element-specific wavelength. |
| Non-Volatile Residue | Gravimetric Analysis | Evaporation of sample under controlled conditions and measurement of residual solids by weight difference. |
| Ester Content (by Saponification Value) | Saponification Titration | Hydrolysis with excess KOH followed by back-titration of unreacted alkali to determine ester concentration. |
| Aldehyde Impurities | UV-Vis Spectrophotometry after Derivatization | Reaction with DNPH to form hydrazones, measured at ~360 nm for quantitative aldehyde estimation. |
| Residual Solvents (e.g., MeOH, EtOH) | Headspace Gas Chromatography (HS-GC) | Thermal equilibration of sample headspace followed by GC-FID analysis for volatile organic impurities. |
