1,5-Diphenylcarbazide is a classic colorimetric reagent specifically used for the determination of hexavalent chromium (Cr(VI)). Offered in ACS Reagent grade, this product is preferred in water analysis, wastewater monitoring, and industrial quality control laboratories for reliable results.

The reagent reacts with Cr(VI) ions in acidic conditions to form a characteristic red-violet colored complex; this property makes it a standard indicator reagent in spectrophotometric chromium determination. ACS Reagent grade ensures the purity and consistency required for analytical applications.

The 25 gram package size is a practical choice for medium and small-scale laboratory use. Its stability at room temperature allows easy storage and inventory management without special storage requirements.
