补充资料：(R,S)α-氰基-间苯氧基苄基(S)-2-(对二氟甲氧基苯基)-3-甲基丁酸酯

分子式：C26H23F2NO4
分子量：451.480
CAS号：70124-77-5

性质：琥珀白色粘稠液体。沸点108℃(0.047kPa)；蒸气压(45℃)3.2×10-8kPa，相对密度1.189(22/4℃)，溶于丙酮、二甲苯、2-丙醇，21℃时的溶解度(g/100ml)：丙醇78，丙酮82，二甲苯181，已烷9，水0.00005。

制备方法：以茴香醛为起始原料，经还原，氯代，氰基化，异丙基化，水解，二氟甲醚酰氯化、酯化等步骤可得到氟氰菊酯。此合成路线冗长，有几步反应收率偏低，原料来源回难，成本高。拟除虫菊酯类杀虫剂，特别是戊酸氰醚酯(氰戊菊酯)，利用中间体2-(对氯苯基)-3-甲基丁酸，直接水解为2-(对羟基苯基)-3-甲基丁酸，再经二氟甲醚化、酰氯化、酰氯化、缩合等反应而得氟氰菊酯。此合成路线收率较高。

用途：该品是含氟除虫菊酯类新品种，化学结构与氰戊菊酯相似。因本品含氟，具有高效，对光和热更稳妥定，同时也能防治螨类蜱等优点主要用于防治鳞翅目，双翅目，鞘翅目等许多害虫，也用于防治棉田的棉铃虫，红铃虫，红蜘蛛，粉虱以及蔬菜，果树的害虫。
