Chitobiose dihydrochloride（Cat No.:I044870）is a disaccharide composed of two β-(1→4)-linked N-acetyl-D-glucosamine (GlcNAc) units, commonly derived from the hydrolysis of chitin. The dihydrochloride form enhances its stability and solubility in aqueous solutions, making it suitable for biochemical and microbiological applications. Chitobiose serves as a minimal structural unit for studying chitinase activity, microbial recognition, and glycan–protein interactions. It plays a role in immune modulation and is used in research on insect development and fungal cell wall metabolism. Its defined structure makes it valuable in assays involving lectins, enzymes, and receptor-ligand binding studies.
