A 20 mL portion of the supernatant was then transferred to a 100 mL round bottom flask and evaporated to dryness at 60°C under reduced pressure using a rotary evaporator. Soil samples were extracted with ammonium hydroxide solution 5% (v/v), concentrated, and reacted with trimethyl orthoacetate (TMOA) in the presence of acetic acid for derivatization. Structure, properties, spectra, suppliers and links for: Glufosinate, DL-Phosphinothricin, 51276-47-2. To evaluate the accuracy and precision, soil samples were spiked with the standard solutions of glufosinate ammonium, MPP, and MPA at 0.1, 0.5, and 1.0 mg kgSoil samples were spiked with glufosinate ammonium, MPP, and MPA (0.1, 0.5, and 1.0 mg kgA simple analytical method was developed to measure concentrations of glufosinate ammonium and its metabolites, 3-methylphosphinico-propionic acid (MPP) and 2-methylphosphinico-acetic acid (MPA), in field soil samples.
Glufosinate is a non-selective, contact herbicide, with some systemic action.

Soil samples were extracted with ammonium hydroxide solution 5% (v/v), concentrated, and reacted with trimethyl orthoacetate (TMOA) in the presence of acetic acid for derivati…
Acetic acid and ammonium hydroxide (both analytical reagent) were purchased from Sinopharm Group Chemicals Co., Ltd. and Beijing Chemical Reagent Company (Beijing, China), respectively.
Boiling Point: 96°C. Glufosinate ammonium dissipated rapidly in soil to MPA in hours and gradually degraded to MPP. 0 View information & documentation regarding Glufosinate-ammonium, including CAS, MSDS & more. [ACD/Index Name] The concentrated derivatives were dissolved in ethyl acetate (2.0 mL) and filtered through a 0.22 Copyright © 2014 Yun Zhang et al. It is moderately toxic to mammals and considered to be a neurotoxin. The representative formulated products for the evaluation were “Basta SL 14”, "Basta SL 18" and "Liberty SL 18", soluble concentrates (SL). The latter can be used in genetically modified glufosinate tolerant 1 OJ No L 53, 29.02.2000, p. 25 2 OJ No L 224, 21.08.2002, p. 5 38.7±0.3 cmOrganic Compound; Pesticide; Amine; Herbicide; Synthetic Compound https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:142851Search Google for structures with same skeleton
Fire Point: > 96°C. The solution was then heated in a water bath at 95°C for 1.5 h to complete the derivatization reaction and evaporated to dryness at 55°C using a rotary evaporator. glufosinate to a non-phytotoxic acetylated metabolite (1) by transferring the acetyl group from acetyl- coenzyme A onto the amino group of glufosinate. A simple analytical method was developed to measure concentrations of glufosinate ammonium and its metabolites, 3-methylphosphinico-propionic acid (MPP) and 2-methylphosphinico-acetic acid (MPA), in field soil samples.
Acetic acid (0.75 mL) and TMOA (1.5 mL) were then added to the residue and the mixture was sonicated at ultrasonic frequency 40 KHz for 5 min.
