Description

General description

Ammonium sulfamate (AS) is ammonium salt containing sulfur. It acts as a flame retardant for polyamide 6 (PA6). AS can be prepared by neutralizing sulfamic acid with ammonia. AS is a hygroscopic compound that undergoes decomposition in the soil to form ammonium sulfate. It also shows herbicidal properties.

Application

Ammonium sulfamate may be used to remove unreacted nitrite during quantification of ceftazidime (CFZM) in either pure form or in pharmaceutical preparations by spectrophotometric method. It may be used in the preparation of ammonium dinitramide (ADN).
