Basic Red 46 (CAS 12221-69-1) Technical Specifications

Chemical Profile

Performance Advantages

Superior lightfastness (Grade 6-7 vs. industry average 5-6) and exceptional wet processing stability reduces dye bath replenishment frequency by 30-40% compared to alternative formulations.

Industrial Applications Breakdown

Textile Dyeing

Preferred for acrylic fibers with 15-20% higher color yield than standard basic dyes. Compatible with exhaust and continuous dyeing systems (recommended concentration: 0.5-2.5% owf).

Paper Coloring

Provides vibrant hue stability in pH 4.5-7.5 environments. Typical usage: 0.1-0.3% based on pulp weight for ledger papers and specialty packaging materials.

Leather Finishing

Shows 25% better penetration depth in chrome-tanned hides compared to similar cationic dyes. Application temperature range: 50-65°C for optimal results.
