What is Disperse Violet 26 CAS 6408-72-6?

Disperse Violet 26, also known as Solvent Violet 59, is an anthraquinone dye with molecular formula C26H18N2O4 and EINECS 229-066-0. It is supplied as a dark purple powder with a bright reddish-violet shade.

Can Disperse Violet 26 be used in high-temperature plastic processing?

Yes. Its anthraquinone structure gives it high thermal stability, and it is commonly described as stable above 260 C and in some polymer systems up to about 300 C. This allows use in extrusion, injection molding, and dope dyeing.

Does Disperse Violet 26 require a carrier for polyester dyeing?

At atmospheric pressure and lower temperatures, a carrier or swelling agent is usually needed because the dye has low water solubility. Under high-temperature/high-pressure or thermosol conditions, polyester dyeing can be performed without atmospheric-pressure carrier dyeing.

Which fibers and materials is Disperse Violet 26 suitable for?

It is used mainly for polyester, acetate, and polyamide fibers, as well as polyester blends. As Solvent Violet 59, it can also color thermoplastics and engineering plastics such as ABS, PC, and PS.

What fastness and solubility properties should formulators expect?

Disperse Violet 26 is insoluble in water but soluble in organic solvents and polymer matrices. It typically offers excellent light fastness around grade 7-8 and high migration resistance in polymers.

Product Description

Disperse Violet 26 CAS 6408-72-6 is an anthraquinone dye, also known as Solvent Violet 59, with molecular formula C26H18N2O4, molecular weight about 422.43 and EINECS 229-066-0.

Synonyms: 1,4-Diamino-2,3-diphenoxyanthraquinone; Solvent Violet 59; 2,3-Diphenoxy-1,4-diaminoanthraquinone; Disperse Red Violet RL.

CAS: 6408-72-6.

It has the molecular formula C26H18N2O4 and a molecular weight of about 422.43 g/mol.

It appears as a violet to reddish-violet powder.

It is insoluble in water but soluble in organic solvents and polymer matrices.

Its anthraquinone structure gives high thermal stability, commonly stable above 260 °C.

It is used mainly for polyester, acetate and polyamide fibers, as well as polyester blends.

At atmospheric pressure and lower temperatures, a carrier or swelling agent is usually needed for polyester dyeing.

As Solvent Violet 59, it can also color plastics and polymer materials.

It typically offers excellent light fastness and good sublimation fastness.

Formulators should match the dye strength and shade to the target fiber and processing conditions.

Store in a cool, dry, well-ventilated area in tightly closed containers away from strong oxidizers.

Protect from moisture and direct sunlight to maintain shade and strength consistency.

Confirm appearance, shade, strength, moisture, heavy metals and residual solvent limits as required.

Use dust masks or respirators and eye protection during handling, and wash skin contact with soap and water.

Confirm packaging with the requested quantity and destination requirements.
