N-Nitrosoglyphosate is the nitrosamine degradation product and synthetic impurity of glyphosate herbicide.

The US EPA limits N-nitrosoglyphosate impurity to a maximum of 1 ppm in glyphosate formulated products.[1] N-Nitrosoglyphosate can also form from the reaction of nitrates and glyphosate. Formation of N-nitrosoglyphosate has been observed in soils treated with sodium nitrite and glyphosate at elevated levels, though formation in soil is not expected at under typical field conditions.[2]
