Description

3,4,5-Trimethylaniline CAS NO 1639-31-2 is a versatile aromatic amine derivative characterized by its three methyl substituents on the aniline ring. This structural feature makes it a valuable intermediate for synthesizing more complex molecules, particularly in the production of dyes, pigments, and advanced pharmaceutical compounds. It is essential for manufacturers and R&D laboratories in the agrochemical, pharmaceutical, and specialty chemical industries seeking to develop high-performance products.

Application

• Key intermediate in the synthesis of azo dyes and organic pigments.
• Building block for pharmaceutical active ingredients and agrochemicals.
• Precursor in the manufacture of liquid crystal materials and electronic chemicals.
• Used in corrosion inhibitors and other specialty additive formulations.
• Research and development chemical in academic and industrial laboratories.
• Intermediate for photographic chemicals and other fine chemical products.

Quality Control

Our 3,4,5-Trimethylaniline is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards and consistent specifications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in the original packaging or equivalent light-blocking material until use.
