Manufacturing Quality Control of 3,5-Dichlorobenzenesulfonamide
| 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 against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., mono-chloro analogs, sulfonamide hydrolysis products) using gradient HPLC-UV with system suitability criteria. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify residual solvents (e.g., methanol, acetone, toluene) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in anhydrous pyridine–methanol medium. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic elements (Pb, Cd, Hg, As) after acid digestion, using isotopic detection for high sensitivity and selectivity. |
| Chloride Impurities | Ion Chromatography (IC) | Separation and quantification of chloride ions (e.g., from hydrolytic degradation or salt residues) using suppressed conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by controlled heating; used for identity confirmation and purity assessment (sharp range indicates high purity). |
| Sulfur Content | Combustion IC (or XRF) | High-temperature combustion followed by ion chromatographic detection of sulfate, or non-destructive quantification via wavelength-dispersive X-ray fluorescence. |
| Appearance & Color | Visual Inspection / APHA Color Scale | Subjective evaluation against water-white standards; color assessed by comparison to APHA scale using Nessler tubes or spectrophotometer. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Determination of inorganic ash content after incineration at 700–800 °C, expressed as percentage weight loss. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using Mie scattering theory to determine D10, D50, D90 values per ISO 13320. |
| Bulk & Tapped Density | ASTM D6393 (Powder Rheology) | Measurement of mass per unit volume before and after standardized tapping to assess flowability and compaction behavior. |
| Microbial Contamination | Membrane Filtration + Culture | Enumeration of aerobic microorganisms and absence testing for specified pathogens (e.g., E. coli, S. aureus) per USP <61> and <62>. |
