Mase, Nobuyuki et al. published new experimental results with the assistance of cas: 2657-87-6

3-(4-Aminophenoxy)aniline is one of ethers-buliding-blocks. Ethers lack the hydroxyl groups of alcohols. Without the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other. Electric Literature of C12H12N2OEthers do have nonbonding electron pairs on their oxygen atoms, however, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds.

Electric Literature of C12H12N2O《Fine-bubble-based strategy for the palladium-catalyzed hydrogenation of nitro groups: Measurement of ultrafine bubbles in organic solvents》 was published in 2017. The authors were Mase, Nobuyuki;Nishina, Yuki;Isomura, Shogo;Sato, Kohei;Narumi, Tetsuo;Watanabe, Naoharu, and the article was included in《Synlett》. The author mentioned the following in the article:

Fine bubbles of hydrogen were employed as a new reaction medium for the autoclave-free gas-liquid-solid multiphase hydrogenation of nitro groups on a multigram scale. Furthermore, ultrafine bubbles were examined by nanoparticle-tracking anal. in organic solvents. And 3-(4-Aminophenoxy)aniline (cas: 2657-87-6) was used in the research process.
