2-Aminobiphenyl is an aromatic amine used primarily in the synthesis of dyes, pharmaceuticals, and agrochemicals, as well as a precursor in polymer chemistry. It also serves as an intermediate for producing carbazole, resins and synthetic rubbers, and is employed in research and analytical chemistry. It appears as a crystalline solid with a faint odor, requiring careful handling due to its potential health risks. This chemical has a CAS number of 90-41-5, a molecular formula of C12H11N (C6H5C6H4NH2), and a molecular weight of 169.22 g/mol. It is stable under ambient storage conditions but carries a signal word of "Warning" for toxicity concerns. Molekula supplies 2-Aminobiphenyl from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
