Hydroxydimethylarsine Oxide

Chemical Designations - Synonyms Hydroxydimethylarsine Oxide Dimethylarsenic Acid Ansar SilvisarSlO Chemical Formula (CH3)2AsOOH. 

Soderquist et al. [10] determined hydroxydimethylarsine oxide in soil by converting it to iododimethylarsine using hydrogen iodide followed by determination at 105 °C on a column (450 cm x 2.8 mg) packed with 10% DC-200 on Gas-Chrom Q (60-80 mesh), with nitrogen as carrier gas (20-30 min 1) and electron capture direction. The recovery of hydroxydimethylarsine oxide (0.15 ppm) added to soil was 91.3 5.1%.

Apart from their pharmaceutical applications, the organic arsenicals are also used as herbicides. The main compounds are monosodium methanarsonate (MSMA) and hydroxydimethylarsine oxide (cacodylic acid). The relatively wide use of these agents is one of the main reasons for concern about their potential hazard to public health. Additionally, bioaccumulation of organic arsenicals in aquatic organisms such as seaweeds, freshwater algae and Crustacea plays a major role in the evaluation of the toxicity of these materials. Consequently, human exposure to organic arsenicals due to the combination of environmental and therapeutic applications is the main cause of the variety of toxic manifestations of these compounds.
