Arsenic (As)	0.5 ppm max
Heavy Metals (as Pb)	Chloride: 11.8-12.8%
Yeast and Mold	Mold count: 100 cfu/g max
Storage Temperature	Ambient, dry
Storage Conditions	Tight container, protected from light and humidity
Allergen & Dietary Statement	Derived from crustacean shell chitin
Intended Use	Active ingredient for osteoarthritis and joint-health supplements and pharmaceutical preparations
Target Industries	Pharmaceutical, dietary supplements, functional food
Recommended Applications	Joint-care tablets and sachets, combination blends with chondroitin sulfate and MSM
Handling & Safety	Standard powder hygiene; avoid moisture pickup
Chemical Class	Amino monosaccharide sulfate double salt
Structural Unit	2-amino-2-deoxy-D-glucose sulfate ester paired with potassium and chloride counterions
Functional Groups	Protonated amine, hydroxyls, sulfate ester group
Ionic Character	Zwitterionic molecule stabilized as a crystalline double salt
Key Features	96.0-104.0% assay window per pharmacopoeial convention; defined chloride and ignition-residue ranges; +54.0 degree rotation reference
Functional Benefits	Reference salt form of glucosamine sulfate used in pivotal joint-health studies; crystalline stability beyond the free sulfate
Mechanism of Action	Provides glucosamine substrate for glycosaminoglycan synthesis and delivers bioavailable sulfate for cartilage sulfation reactions
Typical End Products	Osteoarthritis supplements, joint-health combinations, pharmaceutical preparations
Formulation Compatibility	Compatible with chondroitin sulfate and MSM; avoid strongly alkaline excipients; hygroscopic salts need moisture barriers
Preparation & Dissolution Guidance	Dissolve directly in water or blend dry; keep exposure to humid air brief
Reactivity & Derivatization	Sulfate ester is hydrolysis-sensitive in prolonged aqueous heat; dry-blending preferred
Stability Notes	Most stable as dry crystals in sealed containers; aqueous solutions should be freshly prepared
Usage Precautions	Do not store in open containers; sulfate content drives the ignition-residue specification
Environmental Profile	Marine chitin valorization into pharmaceutical-grade amino sugar
Analytical Methods	Assay by HPLC or ion chromatography; chloride by titration; rotation by polarimetry; ignition residue per pharmacopoeia
