''N''-Nitrosoglyphosate is the
nitrosamine degradation product and synthetic impurity of
glyphosate
Glyphosate (IUPAC name: ''N''-(phosphonomethyl)glycine) is a broad-spectrum Herbicide, systemic herbicide and Crop desiccation, crop desiccant. It is an organophosphorus compound, specifically a phosphonate, which acts by inhibiting the plan ...
herbicide.
The US EPA limits ''N''-nitrosoglyphosate impurity to a maximum of 1 ppm in glyphosate formulated products. ''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.
