Product Name:2'-chloro-6'-(dimethylamino)-3'-methylspiro[isobenzofuran-1(3H),9'-[9H]xanthene]-3-one
English Name:2'-chloro-6'-(dimethylamino)-3'-methylspiro[isobenzofuran-1(3H),9'-[9H]xanthene]-3-one
CAS No.:21121-62-0
Aliases:Thermal/pressure-sensitive red TF-R2, 3-chloro-6-(dimethylamino)-3'-methylfluoran, Red thermal dye TF-R2
Molecular Formula:C25H22ClNO3
Physical Properties:This product is a red crystalline powder, odorless and tasteless, insoluble in water, readily soluble in organic solvents such as ethanol, acetone, and toluene. Melting point approximately 280-283°C, density about 1.32 g/cm³. It develops a red color under acidic conditions and exhibits excellent thermal color-developing sensitivity and color saturation.
Uses:Mainly used as a red color former for thermal recording paper and pressure-sensitive recording paper, working in combination with developers such as bisphenol A to rapidly develop color under heat or pressure. It is also applicable in thermal transfer ribbons, temperature-indicating materials, and functional coatings.
Technical Specifications:
Appearance: Red crystalline powder, free from visible impurities
Content (HPLC): ≥98.0%
Melting point: 280-283°C
Loss on drying: ≤0.5%
Ash content: ≤0.3%
