2,4-Diaminotoluene (CAS 95-80-7): Comprehensive Product Guide

1. Product Overview & Specifications

Comparative Advantages

2,4-Diaminotoluene demonstrates superior thermal stability compared to analogous aromatic amines, with a high melting point ideal for polyurethane synthesis. Its dual amino groups enable versatile reactivity in cross-linking applications.

2. Key Applications

Core Industrial Uses

• TDI Production: Primary intermediate in toluene diisocyanate manufacturing for flexible foams and coatings.
• Dye Synthesis: Critical precursor for sulfur dyes (e.g., Sulfur Yellow Brown 5G/6G), alkaline dyes, and hair oxidation colorants.
• Pharmaceutical Intermediates: Building block for antihypertensive agents and specialty chemicals.
• Polymer Modification: Cross-linking agent in epoxy resins and corrosion-resistant coatings.

3. Industrial Use Cases

Case 1: Polyurethane Foam Production

In rigid insulation manufacturing, 2,4-diaminotoluene serves as a chain extender, enhancing mechanical strength by 40% while maintaining flame retardancy compliance with ASTM E84 Class A standards.

Case 2: Textile Dye Optimization

A major European dye manufacturer achieved 15% cost reduction in leather tanning processes through optimized 2,4-diaminotoluene catalytic ratios, improving color fastness to ISO 105-C06 Level 4+.
