| Personal Care Industry | Added as a solvent or fixative in cosmetics and personal care products | Produced via chemical synthesis or biotechnological methods, followed by purification and filtration to meet application specifications |
| Pharmaceutical Synthesis | Employed as a chiral building block in the construction of active pharmaceutical ingredients | Leverages its chiral structure to react selectively with other compounds under defined conditions, yielding target drug precursors |
| Pesticide Manufacturing | Potentially used as an auxiliary component in certain pesticide formulations | Manufactured via a synthesis route selected according to specific formulation requirements, ensuring compliance with applicable regulatory standards |
| Fine Chemicals | Used as a starting material in the production of other fine chemicals | Processed using methods tailored to the requirements of downstream applications |
Manufacturing Quality Control of (S)-Butyl 2-hydroxybutanoate
| Detection Item | Common Detection Methods | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectroscopy (IR) | By measuring the infrared absorption spectrum of the sample and comparing it with standard spectra, the presence of characteristic functional groups (such as ester groups, hydroxyl groups) in the molecule is confirmed, used for structural confirmation of compounds. |
| Nuclear Magnetic Resonance Hydrogen Spectrum (¹H NMR) | Using nuclear magnetic resonance technology to analyze information such as the chemical shift and coupling constants of hydrogen atoms in the molecule, verifying the structure and stereochemistry of (S)-2-hydroxybutyric acid n-butyl ester. | |
| Content Determination | Gas Chromatography (GC) | Using a capillary column gas chromatography with an FID detector for quantitative analysis of the main component content; suitable for volatile and thermally stable ester compounds. |
| High-Performance Liquid Chromatography (HPLC) | Using a reverse-phase C18 chromatographic column with a UV detector (e.g., 210 nm), suitable for content determination of samples that are not easily vaporized or thermally unstable, and can also separate impurities simultaneously. | |
| Optical Purity / Enantiomeric Excess (e.e.) | Chiral Gas Chromatography (Chiral GC) | Using a chiral stationary phase capillary column to directly separate (S)- and (R)-enantiomers, calculating the enantiomeric ratio to assess optical purity. |
| Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Using a chromatographic column with a chiral selector bonded, achieving enantiomer separation under specific mobile phase conditions, suitable for high-precision e.e. determination. | |
| Moisture | Karl Fischer Titration | Utilizing the quantitative reaction between iodine and sulfur dioxide in a pyridine/methanol system with water, accurately determining the trace moisture content in the sample. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Placing the sample in a sealed headspace vial and heating to allow equilibrium, then sampling the gaseous portion and detecting possible residual organic solvents (such as toluene, ethanol, dichloromethane, etc.) using GC-FID. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Using a gradient elution program combined with DAD or MS detectors to separate and identify process impurities, degradation products, etc., controlling total impurities and individual impurity limits. |
| Optical Rotation | Polarimeter Measurement | Measuring the optical rotation of the sample solution at a specified wavelength (usually the sodium D line, 589 nm) and temperature, used for preliminary judgment of optical activity and configuration consistency. |
| Acid Value/Hydroxyl Value (if applicable) | Titration Method | Acid value: titrating free acids with a potassium hydroxide standard solution; hydroxyl value: indirectly determining the free hydroxyl content through acetylation followed by back-titration, assessing raw material or degradation status. |
