CAS: 71561-11-0; Pyrazoxyfen

该化合物是一种选择性的除草剂,属于青蒿素化学类,主要用于稻田中出现前和早期出世后杂草控制,有效针对年青草和大叶杂草,抑制了焦质素生物合成,导致叶绿素退化和杂草死亡; Pyrazoxyfen 表现出强大的残留活动,确保长期抑制杂草,对稻谷影响最小; 其低应用率和有利环境特征,包括对非目标生物的毒性降低,使其成为综合杂草管理的可持续选择; 该化合物在典型的实地条件下保持稳定,提供各种农业系统的可靠性能; 它的选择性和功效定位是现代稻米种植的宝贵工具.

    标 题 :Synthesis of glufosinate using an amidase-based process
    发明人:ZIMMERMANN GUNTHER; POTT MORITZ STEFAN
    权利人:BASF SE
    摘要:The present invention relates to a method of preparing glufosinate, comprising the steps of hydrolysing an N-carbamoyl glufosinate amide with an Amidase enzyme to form an N- carbamoyl amino acid compound followed by cleaving off the carbamoyl moiety of said N- carbamoyl amino acid compound.
