Manufacturing Quality Control of 4,4'-DIBROMO-4''-PHENYLTRIPHENYLAMINE

Detection Item	Common Analytical Method	Method Overview
Assay (Purity)	HPLC-UV	Quantifies main component using reverse-phase chromatography with UV detection at characteristic wavelength.
Related Substances	HPLC-UV	Separates and quantifies structurally similar impurities based on retention time and peak area.
Residual Solvents	GC-FID	Detects and quantifies volatile organic solvents using flame ionization detection after gas chromatographic separation.
Water Content	Karl Fischer Titration	Measures water by coulometric or volumetric titration with iodine-based reagent in anhydrous methanol.
Heavy Metals	ICP-OES	Determines total heavy metal content (e.g., Pb, Cd, Hg, Ni) via atomic emission spectroscopy after acid digestion.
Chloride Impurity	Ion Chromatography	Separates and quantifies chloride ions using suppressed conductivity detection after anion exchange.
Melting Point	Capillary Melting Point Apparatus	Measures temperature range at which solid transitions to liquid, indicating crystallinity and purity.
Appearance	Visual Inspection	Assesses physical state, color, and presence of visible particulates or discoloration under controlled lighting.
Bulk Density	USP <616> Method I	Determines mass per unit volume of freely settled powder using calibrated cylinder and balance.
Particle Size Distribution	Laser Diffraction	Measures size distribution by analyzing angular scattering pattern of laser light passed through dispersed sample.
Loss on Drying	Gravimetric Analysis	Determines volatile content by measuring weight loss after heating at specified temperature under controlled conditions.
Residue on Ignition	Gravimetric Analysis	Quantifies inorganic residue remaining after high-temperature ashing of sample in platinum crucible.
