Industrial Applications of trans-2-Methyl-2-pentenoic acid
| Industry | Application | Process |
|---|---|---|
| Fragrance & Flavor | Used as a fragrance ingredient to impart fruity and green notes; commonly employed in formulating apple-, pear-, and other fruit-type fragrances | Incorporated directly into fragrance compositions as a base component, or diluted for use in perfuming household and personal care products |
| Food Additives | Used as a food flavoring agent to enhance or modify fruit flavors in food products | Added at trace levels (ppm) to beverages, confectionery, and baked goods in accordance with GB 2760-2024; compliant with FEMA GRAS (No. 3918) and JECFA (No. 1005) safety assessments |
| Organic Synthesis | Used as a chiral synthetic intermediate in Diels–Alder reactions or asymmetric hydrogenation to produce high-value pharmaceutical intermediates | Subjected to selective hydrogenation in the presence of palladium or rhodium catalysts, or employed as a dienophile in cycloaddition reactions |
Manufacturing Quality Control of trans-2-Methyl-2-pentenoic acid
| Detection Item | Common Detection Methods | Method Overview |
|---|---|---|
| Content Determination | Gas Chromatography (GC) | Capillary column gas chromatography with flame ionization detection (FID) is used for qualitative analysis by retention time and quantitative analysis by external standard or internal standard method based on peak area. Suitable for volatile organic acids. Derivatization (e.g., esterification) is required to enhance detection sensitivity and stability. |
| Purity and Impurity Analysis | High-Performance Liquid Chromatography (HPLC) | C18 reversed-phase column, UV detector (typically at 210–230 nm), gradient elution using water and organic solvents (e.g., methanol or acetonitrile) to separate the main component from impurities, enabling assessment of purity and related substances. |
| Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | ¹H-NMR and ¹³C-NMR are employed to confirm compound structure by analyzing characteristic peak chemical shifts, coupling constants, and integration areas, thereby verifying trans configuration and substitution positions. |
| Functional Group Identification | Fourier Transform Infrared Spectroscopy (FTIR) | IR absorption spectrum is used to identify functional groups: carboxylic acid (—COOH) shows a broad peak at ~2500–3300 cm⁻¹ and C=O stretching vibration at ~1710 cm⁻¹; carbon-carbon double bond (C=C) appears at ~1600–1680 cm⁻¹, assisting in molecular structure elucidation. |
| Molecular Weight Confirmation | Mass Spectrometry (MS) | Electron ionization (EI-MS) or electrospray ionization (ESI-MS) is applied to obtain molecular ion peaks [M]⁺ or [M-H]⁻, confirming molecular weight (C₆H₁₀O₂, theoretical molecular weight: 114.14 g/mol). |
| Water Content | Karl Fischer Titration | An electrochemical titration method specifically designed to determine moisture content in samples. Widely used in quality control of active pharmaceutical ingredients or intermediates to ensure storage stability. |
| Residual Solvent Testing | Headspace Gas Chromatography (HS-GC) | Used to detect trace organic solvents (e.g., methanol, ethanol, acetone) potentially remaining from manufacturing processes. Complies with ICH guidelines to ensure product safety. |
| Melting Point | Melting Point Determination Method | Measured using a melting point apparatus to determine the temperature range at which a substance transitions from solid to liquid, serving as a physical constant to assist in identity verification and purity assessment (pure substances exhibit narrow melting ranges). |
