New hapten compositions useful in preparing antigens which may be employed in eliciting antibodies useful in an improved radioimmunoassay for pharmacologically active phenethylamines are disclosed. Particular phenethylamins which are preferably detected by the present radioimmunoassay include the catecholamines such as norepinephrine, dopamine and epinephrine, and the amphetamines.
