Product Name:3,3-bis(1-butyl-2-methyl-1H-indol-3-yl)-1(3H)-isobenzofuranone
English Name:3,3-bis(1-butyl-2-methyl-1H-indol-3-yl)-1(3H)-isobenzofuranone
CAS No.:50292-91-6
Aliases:3,3-bis(1-butyl-2-methyl-1H-indol-3-yl)phthalide, Thermal dye base, Pressure-sensitive dye red
Molecular Formula:C34H36N2O2
Physical Properties:White to light yellow crystalline powder, easily soluble in acetone, toluene, ethyl acetate and other organic solvents, insoluble in water. Melting point approximately 180-185°C, boiling point approximately 680.9°C (760 mmHg), flash point approximately 365.6°C. Exhibits thermochromic and piezochromic properties, developing vivid color upon lactone ring opening in the presence of acidic color developers.
Uses:This product is a commonly used colorless dye precursor in thermal and pressure-sensitive dye systems, undergoing ring-opening color development upon heating or pressure in contact with a color developer to form stable colored products. It is mainly used in the manufacture of thermal recording paper, carbonless copy paper, thermal transfer ribbons, and also applied in anti-counterfeiting labels and functional coatings.
Technical Specifications:
Assay (HPLC) ≥ 99%
White to light yellow crystalline powder
Melting point range 180-185°C
Loss on drying ≤ 0.5%
Packaging: 25kg/drum (fiber drum with inner plastic bag)
