Peroxidases are ubiquitous enzymes that play an important role in living organisms. Current spectrophotometrically based peroxidase assay methods are based on the production of chromophoric substances at the end of the enzymatic reaction. The ambiguity regarding the formation and identity of the final chromophoric product and its possible reactions with other molecules have raised concerns about the accuracy of these methods. This can be of serious concern in inhibition studies. A novel spectrophotometric assay for peroxidase, based on direct measurement of a soluble aniline diazo substrate, is introduced. In addition to the routine assays, this method can be used in comprehensive kinetics studies. 4-[(4-Sulfophenyl)azo]aniline (λ max = 390 nm, ? = 32 880 M?1 cm?1 at pH 4.5 to 9) was introduced for routine assay of peroxidase. This compound is commercially available and is indexed as a food dye. Using this method, a detection limit of 0.05 nmol mL?1 was achieved for peroxidase.

A chromium complex compound represented as the free acid form by the formula (I): STR1 wherein X1 represents a hydrogen atom, a methyl group, a methoxy group or a sulfonic acid group; X2, X3 and X4 represent independently a hydrogen atom, a chlorine atom, a methyl gorup, a methoxy group, a carboxyl group or a sulfonic acid group; Y represents a hydrogen atom or a sulfonic acid group; Z represents a chlorine atom, a fluorine atom or --N30 (R)3 (R represents a C1 to C4 -alkyl group), STR2 and M represents a hydrogen atom or an alkali metal, a process for producing the chromium complex compound (I) and a method for dyeing cellulosic fibers with the same. The chromium complex compound represented by formula (I) is excellent in affinity to cellulosic fibers and in color-yield, build-up properties and fastness properties. These compounds are dyes for cellulosic fibers.
