Improved Syntheses of an Arseno-Fatty Acid (As-FA 362) and an Arseno-Hydrocarbon (As-HC 444).

Robust and reliable synthetic methods have been developed for the preparation of an arseno-fatty acid (As-FA362) and an arseno-hydrocarbon (As-HC444). An improved route to access the starting materials necessary for the new synthetic routes is also disclosed. With these improvements, an increased accessibility to arsenic-containing compounds is anticipated, which may be deployed as standards required for the development of quantitative methods in biological matrices. For the first time, stability data for these compounds are reported. With these results in hand, data on the elimination profile, bioaccumulation potential and patho-behavioral and physiological consequences of these organoarsenicals are planned.
