Industrial Applications of Disodium 4-nitrophenylphosphate
| Industry | Application | Process |
|---|---|---|
| Biotechnology / Molecular Biology | Substrate in enzyme-linked immunosorbent assay (ELISA) | Hydrolyzed by alkaline phosphatase (ALP) to generate yellow para-nitrophenol for colorimetric quantification |
| Clinical Diagnostics | Reagent for immunoassays and clinical chemistry analysis | Used as a chromogenic substrate in automated or semi-automated clinical analyzers for detection of antigens, antibodies, or enzymatic activity |
| Life Sciences Research | Chromogenic detection in Western blotting | Reacting with alkaline phosphatase-conjugated secondary antibodies to produce a visible color signal for target protein localization |
| In Vitro Diagnostics (IVD) | Component of rapid test kits | Integrated into lateral flow or microplate platforms for visual or instrument-based detection of pathogens, hormones, and other biomarkers |
Manufacturing Quality Control of Disodium 4-nitrophenylphosphate
| Test Item | Common Test Method | Method Summary |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and physical state (typically white or off-white crystalline powder), checking for foreign particles, caking, etc. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase column with a mobile phase of phosphate buffer-methanol/acetonitrile and a UV detector (e.g., 310 nm) to quantify the main component. |
| Purity (Related Substances) | HPLC Impurity Analysis | Under the same conditions as the assay, detect impurity peaks before and after the main peak, calculate the percentage of individual and total impurities, and evaluate product purity. |
| pH Value | pH Meter Measurement | Dissolve the sample in water to a specified concentration (e.g., 1% w/v), measure pH using a calibrated pH meter; the value should fall within the specified range (e.g., 6.0–8.0). |
| Loss on Drying | Loss on Drying by Heating (105°C to Constant Weight) | Weigh the sample into a pre-weighed, constant-weight weighing bottle, dry at 105°C until constant weight is achieved, and calculate the percentage weight loss, indicating moisture and volatile content. |
| Sulfated Ash | Residue on Ignition (Ash Content Determination) | Ignite the sample in a high-temperature furnace (e.g., 600–800°C) until constant weight; the residual ash consists of inorganic salts or metal oxides, used to assess inorganic impurities. |
| Heavy Metals | Thioacetamide Method or ICP-MS | Detect total heavy metals such as lead, arsenic, mercury, and cadmium using colorimetry (as per Chinese Pharmacopoeia general methods) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to ensure compliance with limit requirements. |
| Solubility | Solubility Test | Observe dissolution behavior in specified solvents (e.g., water, ethanol); the substance should be freely soluble in water and slightly or practically insoluble in organic solvents. |
| UV Absorption Spectrum | UV-Visible Spectrophotometry | Prepare a solution of known concentration and scan between 200–400 nm to confirm the maximum absorption wavelength (e.g., ~310 nm) and characteristic absorption profile for identification support. |
| Structural Confirmation | Infrared Spectroscopy (IR), Nuclear Magnetic Resonance (NMR), Mass Spectrometry (MS) | Compare IR spectrum with reference standard, or use ¹H/³¹P NMR and MS to confirm molecular structure consistency with the target compound; used for raw material identification. |
