Abstract (en)
[origin: GB2592668A] A crystalline modification I of (3-bromo-6-methoxy-2-methylphenyl)(2,3,4- trimethoxy-6-methylphenyl) methanone (metrafenone) 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 5 in an X-ray powder diffractogram (X-RPD) recorded using Cu—Kα radiation at 25°C: 2θ = 8.6 ± 0.2 (1) 2θ = 10.0 ± 0.2 (2) 2θ = 10.6 ± 0.2 (3) 2θ = 11.5 ± 0.2 (4) 2θ = 12.2 ± 0.2 (5) 2θ = 15.6 ± 0.2 (6) 2θ = 17.3 ± 0.2 (7) 2θ = 20.5 ± 0.2 (8) 2θ = 21.7 ± 0.2 (9) 2θ = 22.6 ± 0.2 (10) 2θ = 25.0 ± 0.2 (11) 2θ = 25.6 ± 0.2 (12) 2θ = 25.7 ± 0.2 (13) 2θ = 27.3 ± 0.2 (14) 2θ = 28.4 ± 0.2 (15) A method of preparing the crystalline modification, compositions comprising the crystalline modification and its use in controlling fungal infestations are also provided.
