The substrate produces a soluble end product that is pale blue in color and can be read spectrophotometrically at 370 or 620-650 nm. The tmb reaction may be stopped with 2 m h2so4 (resulting in a yellow color), and read at 450 nm. A sensitive and specific reagent for the detection of blood, assay of hemoglobin, assay of peroxidases.Quality level: premiumassay: ≥98.0% (Nt)mp: 166-171 °c; 168-171 °c(lit.)Storage temp.: 2-8°C
