Diquat metabolite TOPPS is a common degradation product of diquat. Diquat is a nonselective, defoliant, preharvest, and non-residual bipyridyl herbicide and crop desiccant, normally used as the dibromide salt, to control broad-leaved weeds and grasses. Its activity is based on the liberation of the superoxide anion radical and, subsequently, hydrogen peroxide, leading to tissue destruction by oxidative stress. The herbicidal activity of diquat is more pronounced in daylight, aerobic conditions, high humidity, and temperature.

As per Regulation (EC) No 1107/2009, repealing the directive 91/414/ECC, diquat is not approved for use in the European Union (EU). The maximum residue limit (MRL) for diquat presence in the crops varies between 0.01 mg/kg in most of the commodities to 5 mg/kg for linseed in accordance with Regulation (EU) 2016/1002.

Zastosowanie

The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques.
