2.6- Dihydroxy-3-phenylazo

Chlorpromazine reacts with 9-bromomethylacridine in acetonitrile to give a quaternary ammonium derivative, which on subsequent photolysis yields fluorescent products [136]. The fluorescence is linear over the analyte range of 0.05 to 1 pg. Lumogallion 5-chloro-3-(2,4-dihydroxy-phenylazo)-2-hydroxybenzenesulfonic acid forms a fluorescent ion-pair complex with chlorpromazine in the presence of Al(III) which is extracted (without interference from primary or secondary amines) up to equimolar concentrations [137,138].

It has been found by experiment that substances of the type RX, containing two different haptenic groups, do not form precipitates with either anti-R serum or anti-X serum Alone, but do form precipitates with a mixture of the two specific antisera. This provides proof of the effective bivalence of the dihaptenic precipitating antigen, and thus furnishes further evidence for e framework theory of antigen-antibody precipitation. In these experiments tiie anti-R serum and anti-X serum were made by injecting rabbits with sheep serum coupled with diazotized p-arsanilic add and diazotized p-aminobenzoic acid, respectively, and the RX substances used were l-amino-2-/>-(p-azophenylazo)-phenylarsonic acid-3,6-disul-fonic add 7-p-(p-azophenylazo)-benzoic acid-8-hy-droxynaphthalene and l,8-dihydroxy-2-/>-azo-phenylarsonic acid-3,6-disulfonic acid-7-p-(p-azo-phenylazo)-benzoic acid-naphthalene.
