Industrial Applications of 206659-00-9
| Industry | Application | Process |
|---|---|---|
| Biochemistry / Molecular Biology | Fluorescent probe for protein conformational studies | Applied in fluorescence spectroscopy to monitor protein folding, denaturation, and conformational changes, leveraging the significant fluorescence enhancement of ANS upon binding to hydrophobic regions of proteins. |
| Pharmaceutical R&D | Drug binding site analysis | Used in fluorescence titration or competitive binding assays to screen candidate drug molecules that bind to hydrophobic pockets of target proteins. |
| Life Sciences Research | Membrane structure studies | Applied as a hydrophobic probe to investigate the structure and dynamics of biological membranes and membrane proteins by binding to the hydrophobic core of lipid bilayers. |
| Biochemical Analysis | Enzyme kinetics and mechanistic studies | Employed to monitor intermediate states during enzyme conformational changes, or to quantify hydrophobic interactions in enzyme–substrate or enzyme–inhibitor binding events. |
| Nanomaterials Science | Surface property characterization of nanomaterials | Used to assess surface hydrophobicity and dispersion stability of nanoparticles, including carbon nanotubes, graphene, and polymeric micelles. |
| Immunology | Antigen–antibody interaction studies | Applied to label hydrophobic regions of antigens or antibodies, enabling analysis of immune complex formation through fluorescence signal changes. |
Manufacturing Quality Control of 206659-00-9
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Purity | High-Performance Liquid Chromatography (HPLC) | Using a reversed-phase C18 chromatographic column and a UV detector (e.g., 290 nm), quantifying the purity of the main component via peak area normalization or external standard method. |
| Content Determination | Ultraviolet-Visible Spectrophotometry (UV-Vis) | Utilizing the maximum absorption of ANS at specific wavelengths (e.g., 370–380 nm), calculating the sample content based on a standard curve. |
| Structure Confirmation | Proton Nuclear Magnetic Resonance (¹H NMR) | Dissolving the sample in deuterated solvent (e.g., DMSO-d6) and analyzing characteristic proton signals to verify molecular structure consistency. |
| Molecular Weight Confirmation | Mass Spectrometry (ESI-MS or MALDI-TOF MS) | Using electrospray ionization or matrix-assisted laser desorption/ionization mass spectrometry to measure the molecular ion peak, confirming that the molecular weight matches the theoretical value. |
| Moisture Content | Karl Fischer Titration | Determining trace moisture using volumetric or coulometric methods, ensuring compliance with standards for loss on drying or moisture content. |
| Residual Solvents | Gas Chromatography (GC-FID or GC-MS) | Using headspace or direct injection to separate and quantify residual organic solvents (e.g., methanol, ethanol), complying with ICH Q3C limits. |
| Heavy Metal Limit | Atomic Absorption Spectrometry (AAS) or ICP-MS | Determining total amounts of heavy metals such as lead, arsenic, cadmium, and mercury after wet digestion of the sample, ensuring compliance with pharmacopoeia or industry standards. |
| Appearance | Visual Inspection and Colorimetry | Observing solid color (typically brownish-yellow powder), odor, and crystalline form; comparing with reference standards if necessary. |
| pH Value (in Solution) | pH Meter Measurement | Preparing a certain concentration aqueous solution (e.g., 1% w/v), calibrating the pH meter, and measuring the pH value to evaluate acid-base stability and applicability. |
| Fluorescence Property Verification | Fluorescence Spectrophotometry | Measuring the emission spectrum under a specific excitation wavelength (e.g., 370 nm), verifying its fluorescent probe functionality (maximum emission around 470 nm). |
