(+/-)-DICLOFOP

Application

It is intended to be used as a certified reference material (CRM) for calibration in chromatography and other analytical techniques.The (+/–)-Diclofop CRM can also be used as following: To evaluate the likely enantioselective oxidative stress produced in Microcystis aeruginosa by diclofop acid For analyzing the phytotoxic effects of diclofop acid enantiomers on the plant Arabidopsis thaliana To study the enantioselective toxicity of diclofop acid on the non-target rice Xiushui 63 seedlings In the chiral separation of diclofop-acid using one- and two- dimensional HPLC methods To determine the enantioselective toxicity and degradation of diclofop in three algal cultures

General description

This certified reference material (CRM) is produced and certified in accordance with ISO/IEC 17025 and ISO 17034. This CRM is traceable to primary material from an NMI, e.g. NIST or NMIJ.Certified content by quantitative NMR incl. uncertainty and expiry date are given on the certificate.Download your certificate at: http://www.sigma-aldrich.com(+/–)-Diclofop is a chiral herbicide that belongs to the chemical class of chiral aryloxyphenoxypropionate compounds. The actual herbicidal active ingredient―the carboxylic acid, is released after application through hydrolysis of the ester. It is absorbed mainly through leaves and inhibits the biosynthesis of fatty acids by suppressing the activity of acetyl CoA carboxylase (ACCase). It is used for the post emergence control of wild oats, wild millets, and other annual grass weeds commonly occurring in wheat, barley, rye, red fescue, and broad-leaved crops.It was included on 1st June 2011 to the Annex I of Directive 91/414/EEC by the European Commission Directive 2011/45/EU. It is authorized for use under the EC Regulation No1107/2009, as per the Commission Implementing Regulation (EU) No540/2011, however it is a candidate for substitution.
