A new class of substituted 2,3-naphthalenedicarboxaldehydes (NDA) is disclosed. Such compounds are of the formula: ##STR1## wherein one or more of R.sub.1 -R.sub.8 are various substituting groups. The above compounds react, in the presence of cyanide ion, with compounds containing primary amino groups to form adducts which exhibit a high fluorescent yield and thus are readily detected and measured by fluorometric assaying techniques.
本发明揭示了一类新的取代的2,3-
萘二
甲醛(N
DA)。这些化合物的
化学式为:##STR1##其中R.sub.1-R.sub.8中的一个或多个是不同的取代基。上述化合物在
氰离子存在下与含有一级胺基的化合物反应,形成加合物,这些加合物具有高荧光产率,因此可以通过荧光测定技术轻松检测和测量。
