Industrial Applications of 4-Bromobutyric acid
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthesis of pharmaceutical intermediates for antiviral and anticancer drugs | Bromination to introduce bromine atoms, followed by esterification or amidation to construct the drug molecule scaffold |
| Organic Synthesis | Multifunctional synthetic intermediate for constructing nitrogen- and oxygen-containing heterocyclic compounds | Nucleophilic substitution, condensation, or cyclization reactions to prepare functionalized molecules |
| Agrochemicals | Synthesis of agrochemical intermediates, such as precursors for herbicides or insecticides | Coupling, substitution, or cyclization reactions to convert into biologically active agrochemical products |
| Polymers | Synthesis of functional polymer monomers, such as monomers for degradable polymers | Ring-opening polymerization or condensation polymerization to produce polymers with specific performance characteristics |
| Fine Chemicals | Production of dyes, fragrances, and functional additives | Acylation, alkylation, or coupling reactions to achieve structural modification and functionalization |
Manufacturing Quality Control of 4-Bromobutyric acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample under natural light or standard lighting to determine whether it is a colorless to pale yellow liquid, and check for turbidity, precipitation, or foreign matter. |
| Content Determination | Gas Chromatography (GC) | Separation using a capillary column with detection by a flame ionization detector (FID); quantification is performed via external standard or internal standard method, suitable for samples with good volatility. |
| High-Performance Liquid Chromatography (HPLC) | Utilizes a reversed-phase C18 column with a UV detector (approximately 210 nm); gradient or isocratic elution using water-methanol or water-acetonitrile as mobile phase for precise quantification of the main component. | |
| Purity (Impurity Analysis) | HPLC Method | As above; identification and quantification of individual impurity peaks based on retention time to calculate total impurity content and assess sample purity. |
| GC-MS | Combines gas chromatography with mass spectrometry for qualitative and semi-quantitative analysis of volatile impurities, particularly useful for identifying organic volatile by-products. | |
| Water Content | Karl Fischer Titration | Uses electrochemical titration principles to accurately measure water content; available in volumetric and coulometric forms, suitable for trace water detection. |
| Acid Value / Purity Verification | Acid-Base Titration | Titration with standardized sodium hydroxide solution, using phenolphthalein or potentiometric endpoint detection; calculates carboxylic acid content based on volume of base consumed, suitable for rapid preliminary assessment. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | After sample digestion, specific heavy metal elements such as lead, cadmium, and mercury are measured to comply with pharmacopoeial or industrial standard limits. |
| Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Provides higher sensitivity for detecting multiple trace metal impurities, suitable for quality control of high-purity or pharmaceutical-grade materials. | |
| Bromine Content | Ionic Chromatography (IC) or Oxygen Flask Combustion | Oxygen flask combustion converts organic bromine to bromide ions, which are then quantified via ionic chromatography or argentometric titration to verify the presence and proportion of bromine in the molecule. |
| Residual Solvents | GC (Headspace Sampling) | According to ICH or pharmacopoeial guidelines, detects residual organic solvents potentially present from manufacturing processes (e.g., methanol, ethanol, dichloromethane). |
| Melting Point / Boiling Point | Melting Point Apparatus or Differential Scanning Calorimetry (DSC) | Measurement of physical constants to aid in authentication; since 4-bromobutyric acid is a liquid, boiling point or refractive index is typically used instead of melting point. |
| Refractive Index | Refractometry | Measurement of refractive index (n20D) at a specified temperature (e.g., 20°C) to assist in identification and consistency verification. |
