Chemical Structure
Description
The molecular framework of QR6QV3EC23 621-29-4 Benzene, 1-isocyanato-3-methyl- m-Tolyl isocyanate AI3-28254 EINECS 210-676-0 EC 210-676-0 UNII-QR6QV3EC23 (C8H13NO) is characterized by an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
