4,4-Diamino-2-Methyl Azobenzene (DAMAB) (CAS NO : 43151-99-1)

4,4'-Diamino-2-methylazobenzene (CAS 43151-99-1) is a critical aromatic amine utilized as a high purity fine chemical in the development of photoresponsive polyimides and advanced optical materials, meeting the growing demand for smart polymers within the US aerospace and electronics sectors. 2-Methyl-4,4'-diaminoazobenzene serves as a vital precursor for specialty dyes and pigments, where a general industry purity 98% is the standard for manufacturers seeking to transition from global sourcing to a reliable domestic bulk chemical supplier to ensure supply chain resilience. 3-Methyl-4,4'-azodianiline is increasingly sought after for custom synthesis services by US-based CDMOs focusing on light-sensitive drug delivery systems and molecular switches, requiring pharma/API purity 99% to comply with stringent regulatory standards and maintain consistent performance in complex chemical architectures. As an established dye and pigment intermediates suppliers in the united states, we ensure dependable supply, consistent quality, and complete regulatory documentation, including CoA and TDS across all grades. Beyond supply, we support partners through the entire product lifecycle from route scouting, process and formulation development, and analytical method development to scale-up, process optimisation, and pilot-to-commercial manufacturing. Our teams also assist with GMP-compliant quality assurance, regulatory documentation, and global supply chain and logistics coordination.
