Industrial Applications of 1,2-Benzisoxazole-3-methanesulfonic acid sodium salt
| Industry | Application | Process |
|---|---|---|
| Pesticides | Herbicide intermediate | Used in the synthesis of benzisoxazole-based herbicides (e.g., fluroxypyr derivatives) via diazotization, coupling, and cyclization to produce the active ingredient |
| Pharmaceuticals | Drug synthesis intermediate | Serves as a key building block for benzisoxazole-containing drugs, including anti-inflammatory and antitumor agents, participating in nucleophilic substitution or palladium-catalyzed cross-coupling reactions |
| Dyes and functional materials | Intermediate for fluorescent brighteners and organic optoelectronic materials | Imparts water solubility via sodium sulfonate group introduction; benzisoxazole-based fluorescent dyes and electron-transport materials are prepared by condensation or oxidative polymerization |
Manufacturing Quality Control of 1,2-Benzisoxazole-3-methanesulfonic acid sodium salt
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, form (such as white or whitish crystalline powder), presence of foreign matter or clumps, etc. |
| Identification | Infrared Spectroscopy (IR) | Compare the infrared absorption spectrum with the standard reference spectrum to confirm the consistency of molecular structure characteristic peaks. |
| Identification | High-Performance Liquid Chromatography (HPLC) | Compare retention time with the standard reference to confirm the identity of the main component; can be combined with ultraviolet detector or mass spectrometer for enhanced specificity. |
| Content Determination | High-Performance Liquid Chromatography (HPLC-UV) | Separate using a reversed-phase column, quantify using a UV detector, and calculate the content of the main component using external standard method or internal standard method, ensuring it meets the labeled range. |
| Related Substances / Impurities | HPLC Gradient Elution Method | Use a gradient elution program to separate potential impurities, and calculate the content of each impurity using area normalization method or self-reference method. |
| Loss on Drying | Drying Method (105°C, constant weight) | Place the sample in an oven and dry until constant weight, then calculate the percentage of weight loss to evaluate moisture and volatile substance content. |
| Residue on Ignition | Incineration in a Muffle Furnace | After ashing the sample at high temperature (usually 600–800°C), weigh the residue to determine the content of inorganic substances, reflecting the presence of inorganic salts or metal impurities. |
| Heavy Metals | Heavy Metal Test Method from Chinese Pharmacopoeia | Use thioacetamide method or atomic absorption spectroscopy (AAS) to control the total amount of harmful metals such as lead, mercury, cadmium, and arsenic. |
| pH Value | pH Meter Measurement | Prepare a solution of a certain concentration (e.g., 1% or 10 mg/mL), and directly measure the pH value using a calibrated pH meter. |
| Solubility | Solubility Test | Observe the solubility in specified solvents (e.g., water, ethanol) to confirm whether it meets the solubility characteristics specified in the quality standards. |
| Residual Solvents | Gas Chromatography (GC-FID or GC-MS) | Use headspace injection or direct injection to detect residual organic solvents (such as methanol, ethyl acetate) from synthesis or purification processes. |
| Microbial Limit | Plate Count Method or Membrane Filtration Method | Test according to pharmacopoeia requirements for total aerobic bacteria, mold, and yeast count, as well as control organisms (such as Escherichia coli, Salmonella). |
