Product Name:6'-(Diethylamino)-1',3'-dimethylspiro[isobenzofuran-1(3H),9'[9H]xanthen]-3-one
English Name:6'-(Diethylamino)-1',3'-dimethylspiro[isobenzofuran-1(3H),9'[9H]xanthen]-3-one
CAS No.:21934-68-9
Aliases:Magenta, D5
Molecular Formula:C26H25NO3
Physical Properties:White to light yellow crystalline powder, odorless. Molecular weight 399.48, melting point approximately 180–190°C. Insoluble in water; soluble in organic solvents such as ethanol, acetone, and chloroform. As a fluoran-type thermal dye, it undergoes lactone ring-opening and develops color under heat or pressure in the presence of an acidic developer, exhibiting a red to magenta shade with high sensitivity and vivid color.
Uses:Used as a thermal (pressure-sensitive) dye, it is a functional colorant in red fluoran dyes for thermal recording paper and thermal printing paper. It rapidly develops color upon reaction with an acidic developer under heat or pressure, and is widely applied in thermal recording materials such as fax paper, label paper, and cash receipts.
