Phosphonic acid: Catalog No. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.) (Aminomethyl)phosphonic Acid. The amino-modified nanoparticles were used as precursor, the functionalization was carried out using a derivative of phosphonic acid that undergoes easy formation of a self-assembled, strongly organic monolayer on the nanoparticle surface, and established mechanisms are the chemisorption of 2-AEP on INOPs for the introduction of polar functional groups onto the surface . Reporting after analysis The laboratory has to respect requirements on reporting after analysis of pesticides. The realisation that phosphonic acid derivatives could, under certain circumstances, react with alcohols to give phosphonate mono-esters was made in 1973 at the Stanford Research Institute. … fosetyl/phosphonic acid in various crops related to the use of potassium phosphonates. In analysis, there is no way of distinguishing whether the detected phosphonic acid and its salts originate from the use of an unauthorised plant protection product containing fosetyl-Al or from a fertiliser/plant fortifier that may be used in organic farming. : 13598-36-2 Molecular Weight: 82.00 Chemical Formula: H3PO3 Urgent contact: Shanghai Sunivo Supply Chain Management Co., Ltd.
