O,O'-Diisopropyl S-[2-(benzene-sulfon-amido)-eth-yl]phospho-rodithio-ate.

The mol-ecular conformation of the title compound, C(14)H(24)NO(4)PS(3), the selective herbicide bensulide, is stabilized by a weak intra-molecular C-H⋯S inter-action. In the crystal, chains are formed through inter-molecular N-H⋯S hydrogen bonds.

Chlormequat residues and dissipation rates in cotton crops and soil.

A simple and reliable analytical method for chlormequat residues in cotton and soil was established in this study. The residual levels and dissipation rates of chlormequat in cotton crops and soil were determined by High Performance Liquid Chromatography-Mass Spectroscopy (HPLC-MS). The limit of quantification (LOQ) was 0.
