 Ammonium alginate (CAS NO.9005-34-9) is used of stabilizers; thickening agent; emulsifier; pigment thinner; and gel-forming agent.Also it can be used of the product for the antipyretic and analgesic.Its antipyretic and analgesic effects is fast and strong, so it is mainly used for cold headache, toothache, muscle pain, joint pain and rheumatic joint pain.

Take 4 - amino-antipyrine (AA) as raw material, then by the formylation to be FAA , by methylation to generate FMAA , by the hydrolysis to be 4 - Methylamino-antipyrine (MAA), and at last by the condensation to get: Ammonium alginate (CAS NO.9005-34-9) .

 Ammonium alginate (CAS NO.9005-34-9) also can be called Alginic acid, ammonium salt ; Ammonium polymannurate ; Analgine ; Callatex ; Collatex ARM Extra ; Digamon ; Protomon .It is a high-molecular-weight, hydrophilic colloid. It occurs as white to yellowish brown filamentous, grainy, granular or powdered forms.
