Application

Ammonium sulfate may be used in methyl cellulose precipitable tannin assay to examine wine tannin in finished wine samples.[1] It may also be used in making externally mixed aerosols for analyzing the 1 × 3 tandem differential mobility analyzer (1 × 3-TDMA), which is mainly employed for determining the irreversibility of the hygroscopic growth factor of aerosol particles.[2]

General description

Ammonium sulfate is an ammonium salt commonly used as fertilizer. It can be synthesized by neutralizing sulfuric acid with ammonia.[3] It is reported to enhance the phytotoxicity of several herbicides like glyphosates.[4] It is formed as a co-product during the manufacture of caprolactam, a precursor of nylon.[5]
