Von Endt and coworkers used monosodium methane arsonate as model compound in a study of organic arsenicals in soil and used TLC on silica gel G coated plates to separate monosodium methane arsonate (MSMA), arsenate and arsonite in soil extracts.

Figure 1 Oxidation states of volatile and soluble arsenic transformed by biological systems. pKi represents the equilibrium between the protonated cation and neutral forms of the hydroxyl group of dimethylarsinic acid. pKj represents the equilibrium between the neutral form and anionic form (2). Occasionally referred to as arsenous acid (2). HO—As=0 has also been referred to as arsenious acid (52). The term arsenite often refers to any of the As(lll) oxides. The species will be a function of the solute and the pH. Given that the pKa of arsenious acid is 9.2 (52), the protonated form is most likely the predominant form in aqueous environmental and physiological samples below pH 9. Structure commonly used when discussing arsenite in biological transformations, but is most likely not the predominant form in aqueous solutions. Monosodium methane arsonic acid (MSMA) is the commercially available sodium salt.

Inorganic arsenicals such as arsenic trioxide, sodium arsenite, lead arsenate, calcium arsenate and Paris Green have been used for many years as soil sterilants. Organic arsenical herbicides, in which the organic group is bonded directly to the arsenic atom, have been used extensively for post-emergence control of weeds in cotton. Several of the more important herbicides are sodium cacodylate (monosodium dimethylarsenic acid) and sodium salts of methane arsonic acid. The latter compounds exist in two principal forms the monosodium salt (MSMA) at pH6.4 and the disodium salt (DSMA) at pH10.2.
