Industrial Applications of 3,5-DICHLOROSULFANILAMIDE
| Industry | Application | Process |
|---|---|---|
| Pesticides | Synthesis of fungicidal intermediates | Used as a key intermediate in the synthesis of chloropyrimidine-based fungicides (e.g., triticonazole) via condensation and cyclization to construct the active molecular scaffold |
| Pharmaceuticals | Synthesis of antibiotics and antiviral agents | Applied in constructing heterocyclic compounds for synthesizing biologically active sulfonamide derivatives, with target drugs prepared through substitution and coupling reactions |
| Dyes | Intermediate for functional dyes | Employed in synthesizing high-performance azo or fluorescent dyes; the chlorosulfonamide structure is introduced via diazotization-coupling to enhance dye stability and color fastness |
| Fine Chemicals | Raw material for specialty chemical synthesis | Utilized as a chlorinated aromatic sulfonamide building block in producing flame retardants and polymer modifiers, with functionalization achieved via nucleophilic substitution or polymerization |
Manufacturing Quality Control of 3,5-DICHLOROSULFANILAMIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time relative to reference standards. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection for quantification of common organic solvents (e.g., methanol, acetone, DMF) against calibration curves. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation in pyridine-free reagent; measures water by stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification after acid digestion using inductively coupled plasma mass spectrometry with isotope dilution or external calibration. |
| Chloride Ion Impurity | Ion Chromatography | Separation of anions on a high-capacity anion-exchange column with suppressed conductivity detection; quantified against chloride standard. |
| Sulfate Impurity | Ion Chromatography | Anion separation and conductivity detection following sample dissolution in dilute nitric acid; sulfate identified by retention time and calibrated response. |
| Residue on Ignition | Gravimetric Analysis | Ignition of dried sample at 700-800 C followed by weighing of non-volatile residue; expresses inorganic ash content as weight percent. |
| pH of Aqueous Suspension | Potentiometric Measurement | Measurement using calibrated pH electrode in a defined suspension (e.g., 1% w/v in water) at 25 C; reflects acidic/basic impurities. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid using calibrated digital melting point instrument per USP <741>. |
| Bulk Density | Tap Density Tester | Measurement of mass per unit volume after controlled tapping per ASTM D1895 Method A; indicates flow and handling characteristics. |
| Particle Size Distribution | Laser Diffraction | Analysis of dispersed dry powder via light scattering pattern; reports D10, D50, D90 values according to ISO 13320. |
