The novel water-soluble tetraazaporphin, fluorescent labeling dyes, biological material has been labeled with a fluorescent labeling dyes containing the same, fluorescence analysis method using reagents and those containing them
PURPOSE: To provide the subject compound useful as a fluorescent labeling pigment, useful for the analysis of antibodies, chemicals, DNA, etc. ;CONSTITUTION: A compound of the formula [M is H2, Mg, Al, etc.; Y is halogen,-OR1,-NR22,-SR3 (R1-R3 are H, alkyl, aryl, etc.,); p is 0-2; A is a condensed polycyclic aromatic ring having m substituents; X is O, N; Q is hydrocarbon, heterocyclic ring; m is 1-4; p is ≥0; four (n) are ≥1, respectively; Z is anion, and E is cationic group; or Z does not exist, and E is polyethylene glycol residue, etc.,]. For example, sodium salt of zinc phthalocyanine tetracarboxylic acid. The compound of the formula is obtained e.g. by reacting zinc tetra (n- amyloxycarbonyl) naphthalocyanine in a solvent such as ethanol in the presence of a base such as sodium hydroxide.;COPYRIGHT: (C)1993,JPO&Japio
