| Horticulture | Rooting agent | Used to accelerate root formation during cutting propagation; commonly applied by immersing cuttings in a prepared solution |
| Forestry | Seedling root promotion | Employed in forest seedling production to improve survival rates; applied via soil drench or root treatment |
| Chemical industry | Organic synthesis intermediate | Serves as a raw material for synthesizing other naphthalene-based compounds; participates in esterification, substitution, and related reactions |
| Research | Laboratory reagent | Used in plant physiological studies to mimic auxin activity; handled in the laboratory with precise weighing and solution preparation |
Manufacturing Quality Control of 2-Naphthylacetic acid
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Assay | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column with methanol-water or acetonitrile-water as the mobile phase. Detection is performed using a UV detector (typically at 230–280 nm). The content of 2-naphthoxyacetic acid is quantified by external or internal standard methods, offering high sensitivity, excellent separation, and good reproducibility. |
| Purity Analysis | Gas Chromatography-Mass Spectrometry (GC-MS) | After derivatization (e.g., esterification), the sample is injected and separated by gas chromatography, followed by qualitative and semi-quantitative analysis using mass spectrometry. This method effectively identifies impurities and degradation products, suitable for trace-level impurity detection. |
| Structural Confirmation | Infrared Spectroscopy (IR) | Determines the infrared absorption spectrum of the sample and compares it with reference spectra to confirm the presence of functional groups (e.g., carboxyl, aromatic ring), used for preliminary structural verification. |
| Crystal Form and Physical Appearance | Differential Scanning Calorimetry (DSC) | Measures thermal changes of the sample during programmed heating to obtain information on melting point, crystallinity, etc., used to evaluate consistency of crystal form and thermal stability. |
| Moisture Content | Karl Fischer Titration | Quantifies water content in the sample based on an electrochemical reaction. Available in volumetric and coulometric modes, this method is suitable for trace moisture determination and provides accurate, reliable results. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Employs gradient elution to separate the main component from potential synthesis intermediates, by-products, or degradation products. Impurity levels are calculated using peak area normalization or reference substance methods. |
| Melting Point Determination | Capillary Melting Point Method | The sample is packed into a capillary tube and heated in a melting point apparatus; the initial and final melting temperatures are observed. Used for identification and preliminary purity assessment—pure substances typically exhibit sharp melting points. |
| Heavy Metal Residues | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Following wet digestion, residual levels of heavy metal elements such as lead, arsenic, cadmium, and mercury are measured, ensuring compliance with pharmacopoeial or pesticide residue limits. |
| Residual Solvents | Gas Chromatography (GC) | Using headspace or direct solution injection, this method detects organic solvents remaining from manufacturing processes (e.g., methanol, acetone, dichloromethane), ensuring compliance with ICH guidelines or relevant regulatory limits. |
