<p>Phthalocyanin derivatives which can be used to differentiate basophils from other blood cells, are quaternary salts of the formula:
<CHEM>
wherein each of A1,A2,A3 and A4 is independently hydrogen, sulfonate, hydroxyl, cyano, or a C1-C7 hydrocarbon, optionally containing at least one hetroatom, with the proviso that at least one of A1,A2,A3 and A4 is
<CHEM>
in which R1,R2 and R3 are each independently a lower alkyl, cycloalkyl or olefin of which at least one is C2-C4 and two may join to form a ring; R4 is hydrogen or a C1-C3 alkyl; n is an integer from 2 to 6; M is a polyvalent metal ion; and X<-> is a water soluble anion. </p> |
