 2,4-Dichlorobenzyl chloride (CAS NO.94-99-5) is the intermediate of diclobutrazol which is a fungicide. And also it is the intermediates of MICONAZOLE.

Using azo-bis-ISOBUTYRONITRILE as a catalyst. With 2,4 - dichloro TOLUENE as raw materials for chloride at an appropriate temperature.During the process, you should control the CHLORINE level. And then we can get the production of 2,4-Dichlorobenzyl chloride.

 2,4-Dichlorobenzyl chloride (CAS NO.94-99-5) hasn't been listed as a carcinogen by ACGIH, IARC, NTP, or CA Prop 65. And the toxicological properties have not been fully investigated.
