Main Applications

Dye & Pigment Intermediates

Used as an important intermediate for basic and cationic dyes, including violet, magenta, blue and red dye systems. The ≥99.0% purity specification supports consistent reaction performance in downstream colourant manufacturing.

Pharmaceutical & Specialty Intermediates

Applied in selected pharmaceutical intermediate routes and fine chemical synthesis where a tertiary aromatic amine building block is required. Controlled water content of ≤0.3% helps reduce moisture-related process variation.

Organic Synthesis & Industrial Processing

Suitable for use in specialty organic synthesis, including routes related to aroma chemicals, rubber additives and other industrial intermediates. Handling, storage and transport must follow toxic-liquid and environmental-hazard controls.

Logistics & Packaging

Standard Packaging:

Available on request; suitable UN-approved packaging should be used for UN 2253 / Class 6.1 toxic liquid shipments.

Storage Conditions:

Keep container tightly closed in a cool, dry and well-ventilated area. Store locked up and away from oxidising agents, strong acids and strong bases.
