An assay method which comprises utilizing chemiluminescence of a pyridopyridazine compound of the formula ##STR1## wherein R.sub.1 is a hydrocarbon group or a heterocyclic group each of which may be substituted and R.sub.2 is hydroxy group, thiol group, amino group or a monosubstituted amino group, and when R.sub.2 is a monosubstituted amino group, R.sub.2 may be taken together with R.sub.1 to form the ring; R.sub.3 is hydrogen atom, a hydroxy group which may be substituted, an amino group which may be substituted, a thiol group which may be substituted, a halogen atom, a heterocyclic group, nitro group, cyano group, carboxyl group which may be esterified or amidated, azido group, sulfo group or an organic sulfonyl group, provided that when R.sub.1 is an aliphalic group, R.sub.3 is not hydrogen atom; and X is oxygen atom or sulfur atom/or a salt thereof; and a novel compound of the formula (I) wherein the symbols are as defined above with proviso that R.sub.3 is hydrogen atom, R.sub.1 is a substituted aryl group or a heterocyclic group which may be substituted, or a salt thereof and the production methods thereof.
一种测定方法,包括利用式中的吡啶吡啶二氮化合物的化学发光##STR1##,其中R.sub.1是一个烃基或杂环基,每个基可能被取代,R.sub.2是羟基、硫醇基、氨基或单取代氨基,当R.sub.2是单取代氨基时,R.sub.2可以与R.sub.1一起形成环;R.sub.3是氢原子、可能被取代的羟基、可能被取代的氨基、可能被取代的硫醇基、卤素原子、杂环基、硝基、氰基、可能被酯化或酰胺化的羧基、叠氮基、磺酰基或有机磺酰基,但当R.sub.1是脂肪族基时,R.sub.3不是氢原子;X是氧原子或硫原子/或其盐;以及式(I)的新化合物,其中符号如上所定义,但R.sub.3是氢原子,R.sub.1是取代芳基或可能被取代的杂环基,或其盐以及其生产方法。
