Manufacturing Quality Control of 3-Piperazinyl-1,2-benzisothiazole hydrochloride

Detection Item Common Analytical Method Method Overview
Assay (Purity) HPLC-UV Quantification using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard.
Related Substances HPLC-DAD Separation and identification of impurities using HPLC coupled with diode array detection; relative retention times and UV spectra support structural assignment.
Residual Solvents GC-FID Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents based on calibrated response factors.
Water Content Karl Fischer Titration Electrochemical titration using iodine generated in situ to determine water content by stoichiometric reaction with pyridine/methanol reagent.
Heavy Metals ICP-MS Quantitative determination of elemental impurities (e.g., Pb, Cd, As, Hg) via inductively coupled plasma mass spectrometry after acid digestion.
Chloride Content Potentiometric Titration Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation.
pH of Aqueous Solution pH Meter Measurement Direct measurement of pH in a 1% w/v aqueous suspension using a calibrated glass electrode pH meter.
Residue on Ignition Gravimetric Analysis Heating sample at 700-800 C to constant weight and determining inorganic residue as percentage of original sample mass.
Particle Size Distribution Laser Diffraction Analysis of dispersed particles in liquid medium using Mie scattering theory to calculate size distribution from angular light intensity patterns.
Melting Point Capillary Melting Point Apparatus Determination of temperature range over which solid-to-liquid phase transition occurs, observed visually in a calibrated capillary tube.
Specific Optical Rotation Polarimetry Measurement of rotation angle of plane-polarized light passing through a solution, used to assess chiral purity and identity.
Microbial Limits Membrane Filtration Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli) following USP <61> and <62>.
