Product name: Chitosan oligosaccharide
CAS 148411-57-8
Chitosan oligosaccharide (COS) is the degradation product of chitosan via enzymatic degradation involving deacetylation and depolymerization processes. COS is biological immune inducer which activates the immune and growth system.With cell activation effect.
Chitosan oligosaccharide is helpful to the recovery of damaged plants, root
development and seed germination.
