ABSTRACT:
The present invention relates to chromogenic compounds which are represented by the general Formula (I): ##STR1## wherein R.sub.1 is a sugar group, ester group, hydrocarbyl group, phosphate group, sulfate group or a salt thereof, with the proviso that R.sub.1 is other than .beta.-D-glucuronic acid or .beta.-D-galactopyranoside, R.sub.2 is H or hydrocarbyl group containing 1 to about 5 carbon atoms, X is Cl or H, and Y is Cl or H. The present invention further relates to a method for quantitatively identifying and differentiating a first biological material having enzyme specificity for a first chromogenic compound as represented by Formula (I) above, and a second biological material having enzyme specificity for a second chromogenic compound.
