Title:
A NOVEL FORM OF METCONAZOLE, A PROCESS FOR ITS PREPARATION AND USE OF THE SAME
Document Type and Number:
WIPO Patent Application WO/2020/164287
Kind Code:
A1
Abstract:
A crystalline modification I of 5- (4-chlorobenzyl) -2, 2-dimethyl-1- (1H-1, 2, 4-triazol-1-ylmethyl) cyclopentanol (metconazole) is provided. The crystalline modification is characterized, for example by exhibiting at least 3 of the following reflexes, in any combination, as 2θ ± 0.2 degree in an X-ray powder diffractogram (X-RPD) recorded using Cu-Kα radiation at 25℃ : 2θ = 10.3 ± 0.2 (1) 2θ = 15.8 ± 0.2 (4) 2θ = 20.6 ± 0.2 (5) 2θ = 22.2 ± 0.2 (6) 2θ = 23.3 ± 0.2 (7). A method of preparing the crystalline modification, compositions comprising the crystalline modification and its use in controlling fungal infestations are also provided.
