A compound of the Formula
wherein:
R is an aliphatic linking group of from 1 to 8 carbon atoms and 0 to 4 heteroatoms which are oxygen, nitrogen or sulfur, having from 0 to 1 site of ethylenic unsaturation as the only aliphatic unsaturation, any nitrogen being present as tertiary amino or amido and any sulfur being present as thio;
X and Z are taken together to form oxo or imino or can each be hydrogen;
A is hydrogen, hydroxy, alkoxy of from 1 to 6 carbon atoms, or an antigenic poly(amino acid) or polysaccharide, or an enzyme;
n is on the average from 1 to the molecular weight of A divided by 1000, with the proviso that n is 1 when A is hydrogen, hydroxy or alkoxy,
is, or is a percursor of, conjugates used in the detection of β-adrenergic blocking agents; antigenic conjugates are employed for the preparation of antibodies and enzyme conjugates as detectors. A detection method using the latter is also claimed.
