BHHCT is a multifunctional dye. It serves critical roles in biological experiments, helping researchers observe and analyze cell structures, track biomolecules, evaluate cell functions, distinguish cell types, detect biomolecules, study tissue pathology, and monitor microorganisms. These applications span from basic scientific research to clinical diagnostics. Additionally, dyes are widely used in traditional fields such as textile dyeing and emerging fields like functional textile processing, food pigments, and dye-sensitized solar cells.
