Manufacturing Quality Control of 2-MERCAPTO-5-NITROPYRIDINE

Detection Item	Common Analytical Method	Method Overview
Assay (Purity)	HPLC-UV	Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to calibrated standard.
Related Substances	HPLC-UV	Detects and quantifies impurities by retention time and UV response relative to main peak using gradient elution.
Moisture Content	Karl Fischer Titration	Measures water content via coulometric or volumetric titration based on iodine consumption in pyridine-methanol buffer.
Residue on Ignition	Gravimetric Analysis	Determines inorganic ash content by high-temperature incineration followed by weighing of residual residue.
Heavy Metals	ICP-OES	Quantifies trace metals (e.g., Pb, Cd, Hg, As) after acid digestion by measuring element-specific atomic emission intensities.
Chloride Impurity	Ion Chromatography	Separates and quantifies chloride ions using suppressed conductivity detection after anion-exchange separation.
Sulfate Impurity	Ion Chromatography	Separates and quantifies sulfate ions using suppressed conductivity detection after anion-exchange separation.
Melting Point	Capillary Melting Point Apparatus	Determines temperature range at which solid transitions to liquid, indicating purity and identity via thermal behavior.
Appearance	Visual Inspection	Assesses physical state, color, and presence of foreign particles under controlled white-light illumination against standard references.
Solubility in Common Solvents	Qualitative Dissolution Test	Evaluates complete dissolution in specified solvents (e.g., ethanol, DMSO) at defined temperature and concentration.
pH of Aqueous Suspension	pH Meter Measurement	Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode.
Organic Volatile Impurities	GC-FID	Identifies and quantifies residual solvents using gas chromatography with flame ionization detection and internal standard calibration.
