Crystal Violet Lactone (CVL) is a leuco triphenylmethane lactone dye that appears as a slightly yellow crystalline powder. In neutral form it is colorless; under acidic or developer conditions it ring-opens to form a resonance-stabilized carbocation with intense color. This reversible halochromic behavior is widely used in microencapsulated carbonless copy papers, thermochromic inks, and specialized chromogenic applications. CVL offers high color strength, good compatibility with standard capsule oils and reliable switching in developer systems when properly formulated.
| Parameter | Specification |
|---|---|
| CAS Number | 1552-42-7 |
| Purity (dye content) | ≥ 97% (commercial grades available up to ≥99%) |
| Molecular Formula | C₂₆H₂₉N₃O₂ |
| Molecular Weight | 415.53 g/mol |
| Appearance | Slightly yellow crystalline powder |
| Melting Point | ~ 180-183 °C |
| Solubility | Soluble in nonpolar/slightly polar organic solvents; low aqueous solubility |
Supplied in 25 kg fiber drums or bags with PE liners for industrial use; lab packs available from reagent suppliers. Store in a cool, dry, well-ventilated place away from strong acids and oxidizers. Keep container tightly closed and follow SDS guidance for storage and handling.
