Manufacturing Quality Control of 2,3-Dimethoxy-5-sulphamoylbenzoic acid

Detection Item Common Analytical Method Method Overview
Assay (Purity) HPLC-UV Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, calibrated against certified reference standard.
Related Substances HPLC-UV Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and peak area normalization.
Residual Solvents GC-FID Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, acetone, DMF) per ICH Q3C guidelines.
Water Content Karl Fischer Titration Coulometric or volumetric titration using iodine-based reagent to determine trace water content in the sample.
Heavy Metals ICP-MS Multi-element detection of Pb, Cd, Hg, As, and other regulated metals after acid digestion and dilution.
Sulfated Ash Gravimetric Analysis Ignition at 700-800 C followed by weighing of residual inorganic ash after sulfuric acid treatment.
Chloride Impurity Ion Chromatography Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction.
pH of Aqueous Suspension Potentiometric Measurement Measurement using calibrated pH electrode in a defined suspension (e.g., 1% w/v in water).
Melting Point Capillary Melting Point Apparatus Determination of temperature range at which solid transitions to liquid, following USP <741>.
Bulk Density Graduated Cylinder Method Mass per unit volume measured by pouring dried sample into a calibrated cylinder without compaction.
Particle Size Distribution Laser Diffraction Analysis of scattered laser light intensity to derive size distribution profile for dry powder.
Microbial Limits Membrane Filtration Enumeration of aerobic bacteria, yeast, and mold using membrane filtration and culture on TSA and SDA media per USP <61>.
