Glucosamine sulfate potassium salt

Glucosamine sulfate potassium salt (CAS 31284-96-5, EC 608-599-6) is an inorganic salt form of glucosamine in which the amine group carries a sulfate moiety and potassium serves as the counterion. Also referred to as Potassium N-Sulfoglucosamine or N-Sulfo-glucosamine, it carries no assigned E-code and is distinct from the more common glucosamine hydrochloride and glucosamine sulfate 2KCl salt forms.

In pharmaceutical formulations, it serves as the active ingredient in joint-health preparations, where the sulfated glucosamine moiety is thought to support proteoglycan synthesis in cartilage tissue. In food supplement manufacturing, it functions as an antioxidant and stabilizer, helping to protect sensitive co-formulated ingredients from oxidative degradation during processing and shelf storage.

The material is sourced to pharmaceutical and food-grade standards, with compliance assessed against Ph.Eur. monograph requirements and REACH registration obligations applicable within the EU. Procurement quantities are typically available in kilogram and multi-kilogram packaging; buyers should confirm grade specification and documentation requirements at the point of inquiry.
