Basic Brown 16 is a synthetic organic dye belonging to the cationic dye family, commonly known for its affinity to negatively charged fibers. It is part of the basic dyes group, characterized by their vibrant color and water solubility. Chemically, it has a complex molecular structure, contributing to its effectiveness in dyeing various substrates. Basic Brown 16 typically appears as a dark brown powder in its solid state. It exhibits stability under normal conditions and has a distinct absorption spectrum, with a lambda max in the visible range, contributing to its brown coloration.
