Abstract

X-ray powder diffraction data and unit cells parameters for a monoclinic variety of the popular herbicide 2-chloro-N-(pyrazol-1-ylmethyl) acetyl-2′, 6′-xylidide, commonly known as metazachlor, butisan, and butichlor, is presented [a=7.306(3) Å, b=17.824(9) Å, c=10.728(3) Å, β=98.46(4)°, space group P21/c, cell volume=1381.82 Å3, Z=4]. The four strongest peaks (Irel>25) at 8.87, 7.19, 4.57, and 4.45 Å are quite distinctive, thus X-ray powder diffraction provides a quick, simple, and definitive method of identifying this form of material from other commercially available herbicide products.
