Manufacturing Quality Control of 1,2-DIFLUORO-4-(METHYLSULFONYL)BENZENE

Detection Item	Common Analytical Method	Method Overview
Assay (Purity)	HPLC-UV	Quantifies main component using reverse-phase HPLC with UV detection at 220-254 nm based on peak area comparison to reference standard.
Related Substances	HPLC-UV	Detects and quantifies structurally related impurities (e.g., isomers, dehalogenated or oxidized by-products) using gradient HPLC-UV.
Residual Solvents	GC-FID	Measures trace organic solvents (e.g., dichloromethane, methanol, toluene) by gas chromatography with flame ionization detection.
Water Content	Karl Fischer Titration	Determines water content via coulometric or volumetric titration using iodine-based redox reaction in anhydrous medium.
Heavy Metals	ICP-MS	Quantifies trace heavy metals (e.g., Pb, Cd, Hg, Ni) after acid digestion using inductively coupled plasma mass spectrometry.
Chloride Impurity	Ion Chromatography	Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction.
Sulfate Impurity	Ion Chromatography	Separates and quantifies sulfate ions using suppressed conductivity detection after aqueous extraction.
Residue on Ignition	Gravimetric Analysis	Measures non-volatile inorganic residue after high-temperature ashing (700-800 C) and weighing.
Melting Point	Capillary Melting Point Apparatus	Determines temperature range at which solid transitions to liquid using calibrated capillary method per USP <741>.
Appearance	Visual Inspection	Assesses physical state, color, and clarity of sample against specified criteria (e.g., white to off-white crystalline powder).
Specific Optical Rotation	Polarimetry	Measures rotation of plane-polarized light to confirm chiral purity and absence of racemization (if applicable).
pH of Aqueous Suspension	pH Meter	Determines acidity/basicity of a defined suspension in water or buffer using calibrated pH electrode.
