Description

Benzenamine, 3,3′-(1,3-phenylenebis(oxy))bis- (CAS No. 10526-07-5) is a high-purity aromatic diamine compound with the molecular formula C₁₈H₁₆N₂O₂. Also known as 3-[3-(3-aminophenoxy)phenoxy]aniline (IUPAC name), this specialty chemical features a central 1,3-phenylene core symmetrically linked to two 3-aminophenoxy groups. The compound’s rigid yet flexible ether-linked structure makes it particularly valuable as a monomer in advanced polymer synthesis. With a molecular weight of 292.33 g/mol, this pale yellow to white crystalline powder offers excellent thermal stability and is soluble in common organic solvents like DMF, DMAc, and NMP. Our product is meticulously purified to ≥98% purity (HPLC) with controlled moisture content (<0.5%) for demanding applications in materials science. Suitable for research and industrial use, it is supplied in amber glass bottles with argon packing to ensure long-term stability. Typical impurities are monitored by GC-MS to include <0.5% of any single byproduct.
