Descrição

Descrição geral

Ammonium sulfate is naturally present as a rare mineral mascagnite in volcanic fumaroles and due to coal fires in some dumps.

Aplicação

Ammonium sulfate has been used:

• to prepare mobile phase A for hydrophobic interaction chromatography (HIC)
• as reference material for the thermal decomposition of NH₄NO₃ (S1–S6) thermal decomposition to N₂O (S1-N₂O–S6-N₂O)
• to prepare the stock solution for M63 medium
• as a reagent in molecular biology and chromatography
• in the precipitation and fractionation of proteins
• in the purification of antibodies
• for the crystallographic analysis of nucleic acids and proteins
• in high-performance liquid chromatography (HPLC) analysis of proteins, such as in hydrophobic interaction chromatography
• for Sepharose chromatography of tRNAs using reverse salt gradients
• in long PCR buffer, in PCR lysis solution, and second-strand cDNA synthesis
• HPLC analysis of phospholipids

Ações bioquímicas/fisiológicas

Ammonium sulfate is an inorganic salt, which is mostly used as a soil fertilizer. It is also used as a flame retardant since it elevates the combustion temperature of the material and lowers maximum weight loss rates. This leads to an upsurge in the production of residue or char.
